Here you will learn what a function is in math, the definition of a function, and why they are important.
Functions have applications in algebra, calculus, science, and engineering. We first begin by describing a function as a mathematical machine that takes input numbers "x" and computes output numbers "f(x)".
We then describe the input numbers "x" as being the domain of the function, while the output numbers f(x) are the range of the function. We will plot several functions including linear functions, quadratic functions, cubic functions, and more.
I'm not trying to sell your ego, but if I had math teachers in high school explaining these concepts as you do i would have had at least a Master's degree in mathematics years ago. I look forward to more of your videos.
You’re welcome!
This is awesome. This era nowadays are evolving times.
@ Jon, I understand completely what you are saying. I would be certified as a math teacher as well too!
true that
Yep i agree 100%
This guy just taught me what my teacher could not in 3 months
What grade are you in?
8
@@drew.t.ashton I am in 8 grade and math I have almost F+
bro, i don't even speak English and this statement of you is also true for me
@@Dogoria I'm also in 8th grade and I also almost got an F+ . Very sad
This Prof is a genius, I can't find words to describe his teaching skills. He has really demystified this topic. Bam
Thank you so much!

See this video examination in life never give up-ruclips.net/video/k4w4pak66V0/видео.html
Exactly
@Electra You don't know what you talking about. That's the short form of "Professor" The only mistake is I didn't put a stop there to indicate it's a short form.
This is a teacher. The sincerity and the wanting of the students to know and understand is really appreciated.
for real
I graduated one of top engineering schools, but I struggled through all my math classes , even in HS. If I had the opportunity to learn it the way he teaches, I could have aced my math SAT and had all A in my math classes. Better late than never I guess!
please sir don't stop teaching and making videos like this. You are very intelligent person. I have never seen a teacher like you before !!! THANKS a lot!!!!!!!!!!!!!!!!
I'm 68 and am trying to teach myself quantum mechanics. I am currently reading Schrodinger Equation book and I am so grateful for these videos with this teacher. He is brilliant at explaining things slowly and yet in depth. Can't thank him enough.
You mean your age is 68🙌
It's been a year. How old are you now🫣?
@@Ieyyskyeykryidyi122 how did i see this so early
R.I.P
It’s been a year you 69?
I'm studying for my finals and this is literally saving me! Thank you!
Awesome good luck on your exams!
Goodness me too! My exam will partake in another two days, so I am preparing for it.
I am currently scouring through different videos, untill I found this gentleman.
Me too 🙂
I'm 26 and I feel like I just discovered maths, fun stuff
It ain't fun 😢
@@prof_Sam_G it is actually, if you will change your outlook for life, its gonna be, i used to be very good at math at young age, however loosed some abilities, but gaining it again, and learning a strong foundations, its a pleasurable cause now you understand everything, and u don't do all of the problems by like just knowing formulas, you can deeply analyze and solve it which is pleasuree
Yes
I'm relearning math in my 30s to change careers to data science and this guy helps me so much. I used to think that I was bad at math but I'm not - I've just had people explaining it to me badly.
I'm 14 and math is to me a discussion just like science and physics. I truly enjoy math and my peers despise math idky
You got 5 stars for your knowledge and ability to explain in a way that a dummy like me can easily understand. Thank you Sir.
You are very welcome!
Jason, MathAndScience.com
I real love the man teaching
hey, to anyone who feels hopeless rn, im in college calculus and my dumbass doesn't have the fundamentals down, so im here at 1 am. Im not worried, im just learning. If im out here doing this, you're already doing better than me and should relax and keep on learning haha
Gang
Highkey fw u for that
Scared to fail but motivated by your message, thx bro
i fw heavy bru thanks
Thank you! ❤❤❤ good luck
My gf didn’t understand this, so I found the easiest way for her to understand, thank you.
@Levan Evans may you please help me .l am struggling as well
@@mervismakasi779 think of a function as a method lets say y=x here y is a triangle and x is gonna represent the sides of triangle. So here function is like a machine which is saying that this condition results in x. Fx=x means function of x=x meaning that fx=y as y=x so does fx =x the only difference here is that fx is said as function of x which is equal to y as y equals x .
@@lordx4641 thank you
@@mervismakasi779 sorry to complicate in the last line its simply that fx =y=x the only diff between fx and y is nothing but notations that isbdifferent label (names
@@lordx4641 got it. It's now clear.
Thanks a lot. I'm 39 and still curious with math subjects that I learned over two decades ago. I even bought some math books for high schools, but none of them contains clear explanation like yours.
nice 👍
is there a reason you are studying maths? like a career change? or just for fun?
@@programmingpersistence5716 Initially it was intended for career change, but then I think I will too hard for me to compete with those math graduates. So now it's just for pleasure, just to prove to my self that I can beat it.
@@iwantriharjanto4288 Thanks for replying..am on a similar journey aswell but to improve myself in my field
@@programmingpersistence5716 Are you a math teacher? Good luck then. :)
Why can't you write a book ? Your explanation is so really
Me in 12th grade finally understanding 8th grade maths.
Thanks God for RUclips and this awesome teacher!!i don’t think I need to go to my classes anymore....👏👏👏👏

I am brushing up on my maths and physics to help my teenage grandson and I'm really getting into your videos as much for my own satisfaction.
I wish that you had been my physics tutor at college 58 years ago when I was studying electrical engineering.
I hope to watch all your lessons - most satisfying and enjoyable, thanks.

How are you doing
Sir,I dont know if you would be reading this or not. I just want to say that you're a great grandfather.
You saved my life before my exam thank you
my teacher was to lazy to teach us this so she gave us this video. Byfar better than anything she would have done. Amazing lesson man!
Awesome glad to help. Thank you!
Ahak nang imo teacher tapolan.
@@jhuzordiz8330 he just said that
lol
In a matter of minutes, you make what functions are have meaning and reason. When you have the logic of it, you can further understand the practical application , and this is coming from a 67 yo man. You're teaching, is really at another level. Thank-you.

I really appreciate it!

Many people have learning disabilities and different learning skills. My 9th grade pre-algebra teacher made me sit on a stool with a (DUNCE) cap in front of my class! Ever since then, math was worse than any plague!!! You are one of two video tutors that gave me the confidence and determination to challenge mathematics head-on. Class of 2022!!!
😊
This is what i call an amazing teacher
So happy you liked it!

Seriously the best explanations! Thanks!
Taking function more than 40 years ago, never remembered that it was so easy to understand. Wish I had a professor like you.
I also listen to his videos to help myself, to help my grandson who is in grade 2 now. I need to be ahead of him before he reaches high school 😁 I'm 69 years old, I might not even be around that time, but I don't care. I love these math videos 😃
Professor what's is your address please, I need to be keeping in touch with you,you are really amazing teacher..
I am all the way from Masinde muliro university, Kenya I appreciate your teaching
that's sketch
Wow! Finally a lesson that brings this subject 'down to earth'! I can't thank you enough!
What a wonderful teacher! I needed a refresher so as to help my grandson with his math later today. This presentation did the job PERFECTLY!!!
So happy you liked it!

this is literally the best explanation
Am just full of it, 4 my finol
watching this the night before my exam. thank you #legend

I have never encountered a good tutor as this man. Now am sure am clearing mathematical analysis this semester. Thanks Sir.
Finally, I clearly understand the terminology you explained perfectly, thank you, Jason, for making life easier.
Welcome!
You made me fall in love with calculus, you're amazing keep enlightening us 👌🙏😆
I have to studying this in turkish idk why im here but that just made me understood everything. Woah amazing 🤷🏻♀️🤷🏻♀️😶

Thanks! Back in the 80's I made my way through Math, PreAlgebra, Algebra 1, Algebra 2, Advanced Algebra, Geometry, Trigonometry, Circuit Analysis, Transistor Analysis, etc in the evenings at the local Junior College for about 4 years with a 4.0 GPA.
Life & Family soon became my Priority and I never got into Calculus. So, I figured I did pretty good thus far...how hard could it be? Ha...Calculus is Humbling! Especially if your on your own. Everything always started off with "Function of X"...WTF is that!? Why do they always start off like you already know what that is? Now I know and feel like I can now move forwards :) Your Explanation of the various "Functions of X" is well done and quite Informative too!!!

honestly he taught me more then any other teacher has ever try on teaching me. Thank You!
@ALLINONEMATHEMATICS incredible, even
Hey professor first of all I would like to say ur teaching skill is perfect I liked it very much and my opinion is it would be better if u make a live so that we can ask a question and u will answer as too and I like how u reply for students👏👍
❤❤❤
Im 65 and thought I was too stupid to learn anything math but I see it is completely understandable. I feel robbed by all those teachers who didn’t teach this subject well.
Thank you! It’s never too late to learn!
I was robbed, they are still robbing our kids but I'm not taking it lying down
Omg you have lessons for everything; electricity, science, math. Wow your a genius.
Absolute legend! Thanks for this, you've made mathematic functions easy to understand!
Thank you so much. I am beginning to understand functions a little bit better.

Awesome way of teaching. A Perfect complete guide
Everyone: how this helped them, trs skills
Me: EH BRO WAT A PRETTY PURPLE MARKER
I just started watching it but yh so far so gud I understand so this did help me
im curious, what age do your schools teach you this stuff?
mine at 12
For me 8th grade so 13-14
😮😯😯😯😯 nice explanation
Thank you very much sir that's all I can say because what ever I say it's not going to be enough
This may sound trivial or hair-splitting, but I'd prefer to hear, "A function is a machine that USES values of x to generate y." I think students will relate to that quicker than most other phraseology. In other words, plug in a value of x and the function spits out a value of y. You did a good job. It was lots better than Mr. Bloom the freak who pretended to teach us Calculus 101 & 102 did.
Great video, I'm watching in my time off so I can keep my mind sharp.
Good luck in your studies!

i feel like i know him personally for some reason
Wow this easy. Thank you Mr 💖
sir I am not sure if I can understand the work
I needed this for my assessment thank you soon much I love you for this
I need to know, how we examine relation in a quadratic equation
Wow what a maths teacher.
I am 68 and doing these maths videos for intellectual stimulation and revision of school day maths.
If I had had a teacher like you teaching me maths I would have been ace.
You make maths less daunting and so easy to understand
I will definitely be recommending your courses.
Thank you for the Great Video. Could you kindly share the title of the next video? I want to watch all your videos about Functions in the right sequence. Thanks again for the excellent explanation. 🙏🏻👏👍
Im 13 and just into pyhsics but i need to learn math, then i started to learn math and now i love math more

You are welcome! Good luck in your studies!
Greetings, Eighth grader here
Thanks for your explanation, man
it was clear as water
Thank you! l get it
Function is part of Algebra.? Not Geometry?😮
I have been taught in my college Algebra class and watched a dozen videos on this but I Love the way YOU explain this! Thank you , thank you so much!
I Immediately bought your online program.
Thank you so much!

You're amazing... Keep up the good work.
Excellent, I wasn't really into math in high school and teachers didn't explain these to make sense tbh, now I don't even study anything related to math in uni, nontheless I really like your content and watch them as a leasure activity

I am from Bangladesh. Thanks a lot sir for the great class.........💖💖💖💖💖
FINALLY i learned how the hell im supposed to solve them functions
Nowadays you don't need to go to school and university, if you're determined just with youtube and Wikipedia is possible to graduate at home.
thanks i really learned something today thank you so much i have a really tough time in math and when i watch your videos i can understand it I will be watching more for more math help and it helps because i have ADHD and it grabs my atention and makes me focus i wish i had you as my teacher
You are so very welcome! Please keep at it and I am confident you will succeed!
Thank you so much sir..you're a genius really
Thank you, professor.
This helped me a lot.
omg thank you so much i just finished 5th grade and i am hyper accelerating to 8th grade math and i was having so much trouble on functions and the test is in 2 days but this helped so much thank youuuuu!!!!!
this man has to be the best. i love ur way of explaining. your lesson is amazinggggggggg
So happy you liked it!
Jason, MathAndScience.com
it took him 26mins to explain better than my teacher did in 45mins what is stopping all teacher from being like this? they expect us to answer the way they want without them explaining the way we want
Do these dvds come with worksheets so that we can practice?
Hi, I don't have worksheets for these yet but will making the companion worksheets early next year. Thank you!
math is phylosophy .if we blive in GOD we would or could say god used math science to creat the whole world.math is the mother of all science.and when this teacher telling us the whole cocept ,using the phylosophy of reality.
Thank you so much for this video, I am studying for my midterms and this helped me a lot, thanks!!!
Welcome!
Honestly this teaching is so clear and made it easy to understand. he really wants us to understand every single things here, . Even a nerd like me understood him. I'm in middle of this video lesson and i couldn't stop myself from admiring his truly passionate teaching. Thank you. God bless you....
