Learn Functions - Understand In 7 Minutes
HTML-код
- Опубликовано: 6 июл 2024
- Learning about functions is critical in math, especially in Algebra. Many students struggle with the concept of what a function is and how to determine is a relation is a function. This video will explain in detail the foundation of what a function is in algebra to include how to evaluate a function and what the domain and range represent with respect to functions.

I love how videos like these take a 30 minute in class lecture and notes and turns it into a 7 minute easy to understand crash course
Best part of RUclips

Absolutely, traditional education system has so many flaws, one of them is having to attend a prolonged lecture which extends a 10 minute topic to 30 minutes +.
Lies again? Drive FX Learn Faster
I believe the reason we learn better is because the teachers are tryna keep up the time so they end up moving too fast
Good job explaining functions. Much clearer now. I am 71 years young going back to relearn high school algebra and enjoying it immensely. Hated it in school.
This is how you know you’ve hit rock bottom
What are you talking about ?
Same here…I hated math in High School. Learning is much easier (and fun) when you’re interested. Just like anything in life!
You don’t hate math, you just hate the way it’s been taught and haven’t learned to appreciate it.
why would you do that to yourself😂😂
I will probably have to watch this 20 more times to get it, but I learned more in these 9 minutes regarding functions than I have in all the classes I have ever taken. Thank you.
So true Lol
Agreed
Im glad im not the only one and i have testing next week prayers for me
Agree with you
give up already
Thank you. I am 82 years old and learning Algebra - again - to help the sons of my friend. I couldn't do it without you and the other RUclips teachers because the school books are hopeless. Your clearly explained lessons are very much appreciated.
i love this. It's never too late to learn.
Keep it up.
I think once you understand the use of functions or the way they are used it just makes everything so much easier to understand, some teachers just go into this topic and just give you questions without understanding what functions help with or what they do exactly making the topic just very vague or forgetful that you will need to remember all over again. So I found this video very useful!
U mean every teacher
My teacher gave us notes without explaining them then gave us worksheets to work on
@@liquidlywater3365 My statistics lecturer does the same bruh.😢
Yeah, it’s like an English-speaking Korean who speaks both languages and expects you to understand the language without context clues solely because they know Korean and expect you to know because they gave you a translation dictionary.
Math has to relate otherwise we’re just memorizing hoards of language for the sake of a degree but probably won’t use it again. In essence, it’s useless to some degree for those who don’t directly use it in some practice or trade.
The uses derived from it are helpful but no one’s really applying it if it’s simply memorizing long strings of information. You might as well be learning how to code.
I’m taking algebra 2. I wasn’t introduced to functions until Geometry, my teacher ran by it, so now I have to teach myself in algebra 2. I was so worried about falling behind. You made it click in my head. Thank you so much mr.
This give me a small bit of hope that I’ll pass my math exam tomorrow
Did u pass ?

this video helped me so much with functions! i've been struggling since october and it took 7 minutes to help me understand the basics. Thank you! This channel is awesome!
The MANNER of teaching , such as this is what many of us wish we could have had to listen to as we were learning. This teacher knows how to TEACH .
How is it maths is so easy for some people to understand and incredibly difficult for others? ( like me )
I'm so envious of those who love it and find it easy.
Look Julee Rowley, MATH started 500 years ago. there were many developments that have been made. To answer your question, this is the answer. In math = 1 +1 = 2 , In algebra 1x + 1x = 2x now, admit it , your math foundation is weak because it is in your mind. WHY WEAK? IT IS WEAK BECAUSE , IT COULD BE YOUR TEACHER METHOD OF TEACHING OR YOU YOUR SELF. STYLE OF LEARNIBNG . To be good in math YOU NEED TO CARRY ON ALL THE FUNDAMENTALS / FOUNDATION LEARNINGS IN THE PAST. IT REQUIRES A SERIES OF UNDERSTANDING FROM BASIC RULES TO HIGHER MATH RULES. FOR OVER 500 YEARS THERE WERE MANY STRUCTURES OF MATHEMATICS. EACH STRUCTURE HAS DIFFERENT RULES TO FOLLOW. AND THOSE DIFFERENT RULES WILL SURELY CONFUSED YOU. IN ORDER NOT TO CONFUSE, YOU NEED TO REMEMBER OR MEMORIZE THOSE RULES WITH SPECIFIC APPLICATION. DONT GET ME WRONG I JUST WANT TO ANSWER YOUR QUESTION
People are good at different things! You may be great at something a person good at math may not be good at. We all lack and exceed at certain activities. Though it sucks we all have to be good at one thing to pass school, Don’t worry, you’ll get through it ^^
There are a lot of reasons that people may seem to have an easier time understanding math a lot better than others. Could come from the approach they take or just the fact they tend to do a lot more math than other people resulting in a brain that slowly becomes much more adjusted towards the subject and the type of thinking necessary for it. It's really as simple as that. If you want to to have an easier time with math, then you need to do it more often but with a few extra things to take into account. The brain works just like any other muscle in your body. When you workout, if you aren't pushing your body and having a hard time then you aren't really getting a proper workout. Same goes for your brain. Focus on the areas you are struggling in. Try to properly understand some of the concepts instead of relying on memorization to carry you. Most importantly though, don't give up just because you think math isn't for you or you just aren't meant to be good at it. Everyone struggles with math in some way or another and I don't think there is one person who can truly say they find math as a whole easy without lying.
I find it easy
I think the people that understand it more are able to apply what they've learned to questions without asking "why?" They're able to understand the math at face value and don't need to understand the meaning behind what it does fundamentally.
I signed up to become a member of your Tablet Class Math it was well worth the minimal fee. Having access 24/7 and you elaborate on all the concepts with worksheets that can be printed for future reference. Thanks
That sounds so helpful 😅 I love this guy
What does the tablet class do?
Thank you for emphasizing the topic of functions, using a beginner's approach to explain them. I think it helps almost anyone believe that they can go to another level in their understanding of intermediate and advanced math.
Thanks so much for this awesome channel! My son is a freshman and doesn’t understand Algebra whatsoever. Neither do I lol. Now we’re going to learn together. I appreciate ya!!
I swear random ppl on the internet make so much more sense than my freaking algebra teacher. Idk any more, but I feel so much more prepared and ready for my test and I definitely will look at more of your videos because they seem to be magical and make everything click in my brain.
I was stressing out so much for my upcoming math exam but your videos have been a great help and I’m able to understand the math better. I’m no longer stumbling through my algabra class thank you so much!
You should have been my maths tutor! You made it sound so simple and now I realise that it was that simple.
I believe some maths teachers complicate for the students when they could have kept it simple! Thanks buddy 😊
I'm in my calc class and I havenever learned what functions are. This cleared up a lot. Thank you so much.
Samee 😂
sometimes its funny to think why we didnt want to learn it earlier
same! was just thrown into this mess and i dont even know who f of x is
I love your teaching style. Showing different ways to understand a topic really helped me. Thanks.
Thank you so much!!
I’m a sophomore in college, working on my degree in business management and I was so lost
in my survey of calculus class.
Thank you for your videos.
I teach Algebra 1 & 2, and Geometry at an alternative High School. I love your organization and explanations. Good stuff! Thank you!
This was so much more informative than my required readings, I’m taking college algebra and I’m so lost and just trying to keep up each week. Thank you for this video!
I feel that pain lol
Did you pass bro? I just started and I’m so LOST.

Thank you for exploring the core fundamentals of this challenging topic.
Me I'm 78 . Maths was my favorite subject. Todate I'm still following the maths lessons in the U-TUBE. I'm simply inseparable with it
Well done. Thank you for explaining it so simple to the father of a home schooler.
Thanks for this, I have a functions test tomorrow, this helps a lot :)
Thanks, i am trying to recuperate the content that i missed in that 2 years of EAD, you are helping me very much
I'm taking a math placement assessment, as I have gone back to college in my 30's. Its been a long time since I've been in school, so I appreciate the video!
Nice job explaining and helping me for my finals test this year😃
Man the same
Same
same today is my final test
How did y’all go?
Thanks. This was a simple, clear explanation I needed.
Great job explaining. Out of high school, but still enjoying math. New subscriber.
Great video! During my teen years I've always had a hard time trying to understand what functions are and what purpose they serve up until I became a software engineer. Now I'm using functions for basically everything in my line of work...
I am starting algebra 1 in 8th grade this year and I have been really stressed out about it and this video helped me a ton on what functions are, thank you so much
Same here
I did it and understand o will have a test in 3 days
@@greetings434 think about an airplane going to an airport, it can’t make two final destinations so 3:4 and 3:5 wouldn’t be a function but 3:4 would be a function so 3 just can’t have 2 outcomes
thanks, im on my way to learning integrals and this was very helpful!
Oh thank the lord I found you!!! I watched so many videos on this topic and I was starting to fall into despair because I wasn’t able to comprehend. I am truly great full! Thank you.
I’m a 17 year Special Education Teacher that is teaching Algebra this year. Thanks for the help!
I watched like 3 other videos before this thank the lord you exist 🙏🏼
Really grateful for this outstanding video. Where were you when I was in 7th grade?
This was edifying. I am a bit delayed on finishing GED MATHS and this topic was unclear for me, but thanks to your good explanation, its become not just understandable but fun.
Thank you for this! My son is struggling with grade 11 Maths. This will help him a lot
Thank you, I'm about to take college algebra... I'm worried about failing so I decided to look up some videos to ensure that doesn't happen. This was very helpful.
Half an hour of Maths everyday before bed , just do a couple problems , and you will never struggle in class again as long as you're consistent
That was incredibly helpful! Thank you
Thanks a lot i learned it real quick within those 7 minutes, your a absolute life saver thanks a lot it really helps for those to earn quick.
Great explanation of functions! It's a lot more clear now.
Thank you! I am going into 8th grade and taking algebra 2, I am a little paranoid since I’m scared I will forget everything. There seems to be a lot of different branches/ways to learn it when it comes to algebra. But I wrote it all on notes and it makes a lot of sense so far! I will be watching more vids, Thank you againn
What school you go to cause algebra 2 is taught in 9th through 11th grade
@@kendrickkartier i Am in 8th grade and im taking algebra 2 , and science Regent's, its an Honor class
Tried to watch this but my tablet wouldn't function.
Hahahahhahaha
No puns
Thank you for taking the time to make these videos, they help so much! God bless you
Interesting way of teaching. I might actually use one of your methods when I teach my learners. I like. 🌱
Video starts at 1:11
👍
Thank you so much! Cramming for a first-day college algebra test right now and this really helps.
I appreciate you making this video! I’m currently taking “College Algebra -Functions & Modeling” 8 week course 😫 help!
Currently reviewing for pre calc as I felt unprepared for the first few days and I am on my journey to develop a better understanding to become more successful in the class.
I'm not going to lie, but you're amazing... 😊 Honestly, I didn't understand this topic before, but now I do... You explained it far better than my teachers😁, I'll be writing my math exam in 2 days, and I basically do not understand most of the topics... I'm grateful for what your doin sir🥰 your a big help, and I'll be looking through all your videos... to understand everything... 😊 I'm lucky I stumbled upon this video😅 I was really struggling😅
me too im so glad
Wow you made it look easier than my math teacher did
Thank you Sir i understood by just watching it once🎊this is the best function video so far.
Thanks to you I understood the function problem in just this little time of watching this video. I never been one to be efficient in math. I still have more learning to do. This video helped me to understand how to find the function of the x value and get the answer to y thank you.
Thank you, I'm horrible at functions and I understand it finally.
Do you just a pick a random number ?
Your videos are so useful. So......addictive, lol. Question : what real life applications would use this concept of a function?
functions are used all the time in many jobs
Yeah as much as I hate them they could be used to predict things
I know this is not useful in our future, but I find these interesting. I love math. Thanks for helping me understand.
I'm studying for my 2nd Bachelors degree (and Double Majoring) in Special Education (Mild to Moderate) and Elementary Education....and suck at math. I'm currently in Math for Elementary Educators 2 (out of 3). This really helps. Thank you.
"All functions are relations but not all relations are functions." My brain crashed.
its like saying a keyboard is a hardware but hardwares arent necessarily keyboards
@@taehyungshands ohh so it’s basically saying that all functions fall into relations but not all relations fall into (or only limited to) functions, bc functions is a subset of relations meaning there’s more to it
@@kevanthelemon4054 yeah, theres different types of way to express relations, like domain and range, etc.
spent like half an hour processing that 😢
I learned more watching this than what my teacher taught
One simple head injury & I I've lost so much. This is definitely helping me, thank you.
Great Job explaining functions short and simple, thank you.
The mandem was doing math innit, thank you my guy
lmao
i’m preparing for semester 2 that starts in three days
What stage of study are you and from which country ?am I from Iraq 🇮🇶🇮🇶😊
Your teaching has aided me a lot. Thank you
This has refreshed my mind. Smooth and efficient explanations.
Function = equation with domain x.
so...what is a function lol? Is it just another way to write y? Or is it something else? Like saying the function of 2 is 13 means what? Or is it (similie) like a machine where you put in an x values and get y values out? I don't understand why ppl would make an another word(function) to write out y
OMG
THAT IS SOOOO MY QUESTION MAN!
I too don't get why people have to make things so frigging complicated when at the end of the day, they both mean the same thing. If f(x) is the same as y, then just use or write y. Like bruh
Oh my god?? This is so easy? Why did I struggle so much at school🥶 Thank you so much! Your video has helped me alot
I started watching this video with zero information of functions. Now I am leaving this video knowing what functions are. Thank you for this video.
Mine is pre algebra
Thank you so much. I am a student. We are getting ready for the next grades math and the teacher sucks at explaining. This helped a lot!!
Great video every step was explained no skips as many teachers tend to do! 😅Thanks! 👍🏽
I’m just here because I didn’t study for a test I have in a few hours, I’m so fucked if this doesn’t help😭
SAME
"Don't feel bad, a lot of students struggle with this topic aswell"
I'm the only one in my class not knowing how to do it🧍♂️
Ur the average one in a place of smart students , it's okay this video has come in clutch for u
Girl don't even worry half my class doesn't get it either maybe you're just from a smarter class or something
You said fx means y. Y is range, but you said it's domain. Please clarify
x variable for domain and y variable for range
@@djstarseven ...say ya have (x-2)^2. Why's the graph moved to the + side??
I love your classes! Thanks for all your help.
Thank you so much, very well explained. Great refresher!!!!
i HATE functions and graphs
Agreed
Real asf
No
Agreed
😔😔and they always like always appear
I get everything just don’t get how he got 2 from X
He just took 2 as an input in the function.
My same problem rn 😢😢😢
It’s not 2 from x. Think of it as what is the value of y or f(x) when x = 2. Then you plug in the 2 anywhere there is an x and solve for y. You can put any number in the x to solve for the y.
@@greenhope4171he made up the "2" as the input of the function to replace x....if we did the same with "4" what do you think the answer would be?
Excellent job. Congratulations
Thank you for reminding me the fundamentals about function, Sir. Really appreciated it. Sir, may I know what app did you use to explain in this video? Thanks in advanced.
I’m here cuz I didn’t listen in class🗿
real
I’m here to prep for state testing lol
A hour and 47 minutes before the exams.
😂😂 seriously
Sha same here😅
Ik I'm gonna forget this
Thank you so much!! you really cleared to me the main fundamental of this topic that I couldn't understand.
Hi. I'm Polish but I don't understand videos about function in my native language, so I thought maybe someone had made a video that would help me understand this topic, but in another language. So... here I am! And now I understood. Thank you.
This is my worst part of math
Same😄
what dose the f do?
It denotes “function of x” or “function of the domain”
@@ooohhenrybmblm So is it just there for labeling basically?
@@graciemosko1059 in a sense yes , but the real technical meaning is to give a value to the variable x .
This is great for my GCSE further maths, thanks!
thank you, this makes me much more confident for an upcoming test.
I’m here because my teacher can’t explain well

Very nice and I could see myself enjoying your class.
Thank you. You help me so much in my College Algebra
I thank you for the clear explanation you presented in the video and I can understand better.
Thank you 55yrs old as an adult I'm fascinated with the topic hope to study and appreciate you creating this channel ⭐
DAMN
Thank you! This helped me out a lot. I never worked with a function before.
Amazing explanation! Functions sound very like Functions in programming language.
