Is this function inverse, sir? f^-1(x)=3√x? Thanks again sir
I have a question. Is the second example an Inverse function? Shouldn't it be one to one function only?
@@ifgosdjjhgjiuzahgiuwgr4137 sometimes when you inverse a function, the inversed graph is no longer a function, take y=x^2 for example
you just explained in 2 minutes what my math teacher failed to in 2 hours.. thank you
What is your grade?High school or elementary?
@@user-xj7ms2hy7l You're right thanks for showing me how to be mature. I'll go try starting an argument on youtube later
Math class for two hours damn
same, i feel u
My G💪💪Have understood something that I had failed to understand in a whole semester
after watching this video, my skin is clear, life is good, and I'm feeling blessed.
Lol i can relate...
your skin clear now huh
I can see your skelaton
No cap
@@marcomartinez89stress gives you acne, in case you missed the go comment’s point.
can you teach my algebra teacher how to teach please
Same heree oof
SAME😔😔😔😔
That's basically why I'm here.
Same right here😓😓
Lol same prob with my teacher
literally having my Finals math test in about 30mins, you just explained this quite easily and i actually understood it quickly.
Good luck ! I hope it’s going well
How did you do
Yeah but how did you do
i have my exam in two days....idk i dont have an ad math background and just started some revision lol, this vid helped alot ! how did u do btw?
THEN WHY AM I REWATCHING THIS 10 TIMES AND STILL DONT UNDERSTAND WHAT KIND OF BRAIN DO I HAVE 😭😭😭🙄
Yes the videos from 2006 are helping
I know right ! Lol. And it's all free
❤️
i can literally memorise the ad better than the formulas i have to memorise
Lol I fucking hate that ad
lmaoooo u right
In 11 minutes, you just explained what i've struggled the whole morning to understand. Keep up the great work! :)
His voice is soooooooo soothing and calm. He knows when and how to speak, to clearly get his points across! I wish he was my Precalculus tutor! I wish I knew his name! Thanks man!
The side effects of having a bad math teacher: watching math videos on youtube
Khai Vo doing it the night before a test lol teacher doesn’t teach shit
@@noluck4678 omg mood. I have a test tomorrow and I'm watching this before I sleep and try answering similar questions tomorrow
@@yumitsoo
I hate when they don't tell you to round or not so you get points off or the entire question wrong, I hate my life my stupid brain
No
@@yumitsoo no
Bro, you are a blessing in this world, can't express how much we love you. Long live Organic Chemistry Tutor
he died?
@@kingdunlap1908 no lmfao
Struggled with these kinds of equations for 2 years, 2 YEARS. Thanks for making this explanation easy to follow and nicely placed out. 👍
Same.
Feeling when u get to college and gotta take a precalc review and u don’t remember shit
I didn't even need to watch the whole video, within the first minute exactly at 1:04 it all clicked and I understood something that 3 different teachers in real life couldn't properly teach me. Thanks a lot.
this guy is the best, period.
The dude teaches like my former math teacher, who made me feel like a math genius with his teaching method.
Lmao your yt name correlates to your comment
I’m in pre calc and myself and a lot of other people in my class are struggling to understand this. My teacher teaches so fast and doesn’t really bother to make sure everyone actually understands what he’s trying to teach. This video was a godsend. Thank you.
I've been watching your videos for the past two years. The reinforcement to topics I learned over twenty years ago are well explained. This has served as a great opportunity to retain important math concepts that never go obsolete.
same ive been watching his videos for 3 years now and he always has something new
You don't use big words at random times and do it all in chronological order which makes it so much easier for me to understand😊
Fam you telling me your teacher doesn’t give it to you in chronological order
@@truthdetective4925 Nah, he skipping all over the place, placing the domain after he has already done the whole equation
Amazing how proper instruction can actually help one understand the subject matter.
there is just a thing with your voice. It sounds so refreshing and chill. Makes me acc like math. You explained everything so well
I wish you were my school teacher. My school teacher is always complex in explaining and make me feel like an idiot. You just made mathematics look simple to me I feel like a smart kid .
So all of us here have bad math teacher huh
No we don't all have a bad Math teacher. Mine js great! I just can't be bothered to search through the long recordings of the lecture and go through people asking questions throughout. That takes too much time
My teacher is so bad that I swear the first minute of this video helped me more than a 20 minute video from him
Serious time
My teacher, doesn’t properly teach.
Spends a day per topic.
Test on as soon as we’re done with a chapter.
Assumes we’re all understanding.
Hmm, it’s a fast class. And I just can’t keep up.
Your videos have helped me a lot!
yall know when the math final GRIND comes around, this guy is my lord jesus christ
literally struggling to answer a question and this video immediately helped me understand. thank you my guy!
So helpful in a time when I can’t even see my algebra teacher
bro explained my topic that i've been working on for 5 DAYS of wracking my brains out in 1 minute and 14 seconds. life is good mate
DANG IT! I was watching then Karlie Kloss came on saying how to make a website with wix! Appart from that, great vid!!!
Wtf r u watching this
Ratio
Ohh ur here
A minute in and i already understand better than what my algebra teacher “tried” to teach us
Sir you are a life saver. Thank you from the bottom of my heart, many might not see this. But teachers like these save the lives of students.
Usually I wouldn't be watching these videos since I understand in class, but online classes are burning me out, which made me go here. My previous year's math teacher attaches your videos for us to learn our lessons in advanced. This year, my current teacher only just does lectures and sends us PowerPoint copies of the lectures (not saying that it's wrong, because that's my current teacher's teaching style).
Like I said earlier, I usually understand the lessons once discussed, but online class burn out didn't make me listen to class at all, or motivated or keep me focused. And that burn out brought me back here.
I would like to sat the videos may be simple, but I find it entertaining with how simple it is.
Anyways, I better stop typing this comment before I distract myself from this lesson since my homework for this is due for today!
in 11 minutes you explained what my math teacher couldn't. this is very helpful, thank you!
Dude you have never failed me! From high school and now college
2:36 Was able to do my math problem after this point, That's all you had to say, and it helped me immensely, thank you.
you are a god sent man thank you! I just started my first year of biomedical science but I need to catch up on some of the maths and your videos makes me not want to throw myself off a building!
omg thank you for all of the great examples and not just leaving us with one trash problem while walking away with the middle finger and saying good luck 😭
Thank you so much, since we have converted to digital learning and we haven’t started using zoom yet for online classes because of the pandemic you are my go to source for all of my questions and they are always answered.
I love your easy style and managed to follow you easily even though i've never done this before, thank you
I had DAYS trying to understand this, the first 2 minutes were enough to understand this!! thank you sm
It’s amazing how this guy could teach me this in 1 min and 11 sec.
May you pls help me with this
f(x)= 3x-3

wow very interesting, i am gonna good at mathematics, thank you sir, even i don't see your face,
i have CAT, this next week, promise you success, cause it's been long days without understand this
You’re an angel!!! I’m trying to revisit all the material I learnt back in high school and your videos are such a blessing.❤️
this is so easy, I wasn't expecting it to be this simple. Simple math like this makes me feel a little smarter.
This man saved my life. My math teacher is fine, but his english is absolutely horrible and i couldnt understand anything, now i did tysm and kudos to you
Thank you so much for this video! I genuinely had so many difficulties understanding this for literally months since it was first introduced in my school and tutoring place. All my friends seem to already understand this concept and I felt really left behind and shameful that I didn't quite understand this concept yet. I didn't expect watching an 11 minute explanation video on youtube would give me my sudden eureka moment, but I absolutely did and it felt otherwordly. It just goes to show that you don't really need to spend a ton of money on tutoring to be able to understand and learn things. It's currently 11PM and I have a math test tomorrow so watching this is really helpful. I will be forever in your debt.
I truly thank you from my heart for all of your hard work and everything you do to help us. Thank you ! ❤️
I'm from Brazil, I learned a lot more from your explanation than from my teacher; I really enjoyed the class.
dude thank you so much, you explained in 11 minutes what I had been confused about for a week. you're a lifesaver
best in the whole world. thx for explanation
Thanks so much for this, you are a good maths teacher.
Thank God for this guy. The textbook my school prescribed for us I couldn't understand it. This guy made me understand this. Thank you
this is the only channel i will watch the ads for cause he deserves it
The amount of trig teachers who dont know how to teach and the people here are both amazing and sad as hell.
You make it so easy. Thanks!
I sometimes wonder why learning this on school is tough but watching vids here is easier than listening to the teacher teaching this.
The way you taught this concept it was so clear! For the first time in my life i understood maths so easily! Thankyou so much!
After the military I decided I wanted to go to college. I'm in my late 20s in remedial math. I thought I was going to major in CS. Although I have an A in my last remedial class, I think I'm too dumb to continue in CS. I'll be switching my major to something in the humanities. Sometimes my math homework makes me want to cry. I'm done trying to force something that I'm just not very good at. I'm always the top student in my liberal arts classes. I guess I'll stick to what I'm just naturally good at.
Alex Ledesma wishing you luck. I sympathize with your struggle in math. I find math beautiful and fascinating but cannot manage to be good at it.
what's CS
Explosive Elephant It stands for computer science.
@@icesnowflake5510 ah thank you
Explosive Elephant Np!
was about to kms, this vid helped☺️
Bruh I spent so long trying to figure this out and this man taught me in the first two minutes of this video
At the varsity, my professor taught algebra like I was already doing a PhD. Thanks for this simple version
TLDR: just swap the x and y. Y = 3x + 4 becomes x = 3y + 4 just get the single Y by itself and you are done.
1:44 Finally.... softh!
Not me struggling to remember how to solve for inverse for almost a year and this guy removing my doubts in a matter of minutes
MR. Organic Chemistry Tutor, thank you once again for another smooth explanation on How to Find the Inverse of a Function.
Ah yes the organic chemistry is strong in this one
Is there a order to how you arrange after cross multiplying? Cuz i just crossed multiplied, got the exact same answer but with inverted symbols. (Last problem)
same here, idk what it is
nvm, its nothing to worry about because both functions are the same.
Amazing video. You need more subscribers!
These comments make me feel like I'm not alone. I feel so depressed trying to understand my professor and then I come here and my confidence is boosted SO much!!!
Do u have a video of graphing inverse function?
Plug in random x values once you solve it and graph it like you would graph a regular function.
thank you so much
*you don't even ask for any subscription but you have a lot.that deserves to you.*
I can't thank this person enough for everything they've done for my education, from pre-calculus to organic chemistry, my degree and future degrees are because of The Organic Chemistry Tutor, Khan Academy, and Quizlet, the holy trio.
Who else is here in 2020 during online school because teachers cant teach worth a crap
lol, same, i feel dumb when im the only one who doesn't understand in my class
Jillian_star my teacher just sucks 😂
@@Icy_815 samme,
i mean, how did our teachers even get a teaching degree?
Jillian_star I’ll ask a question and he’ll pause and then keep teaching
I have an exam the morning I'm watching this😢
how was yur xm??
I am sooo going to advice my whole school about you I don't think I would be able to pass my math exam tomorrow without you
I have no idea if you will see this comment but you literally have the greatest tutorials ever. Thank you!!
How do you inverse with fractions?
AniJam you reverse the numerator and the denominator and if there is like subtraction or addition you just do the opposite of what it is. So if it was like y= 3/5x + 7 it would be y= 5/3x - 7
Caution510 _ thanks
i will pass precalc. say it with me. Love you, Muah 💋
After 5 years this video still helping, thank you so much!!!
I swear to god you are a miracle it literlly took me 2 hours on your channel to understand everything I have been trying to understand the past year THANK YOU SOOOOO MUCH like really dude your videous should hit 30 million subscribes it's more usefull than story telling or funny videous
how do you get rid of a cubed root?
DomoKilla cube it
cube both sides of the equation.
Cube both sides like she said
my question is :
x ≥ __
ur the GOAT, I’m in precalc honors and my teachers teaches for quick I can’t understand her, u just cleared everything up
I was skipping school. That's why I missed to learn mathematics and so now, that I'm focus on my studies? It turn CRAZY. Thank you so much. You made math easy.
there is literally no point in switching the x with y
well... im studying for finals and your 99% of my review and refresh on stuff i already learned (also u) ur the goat
Man you have a talent of teaching , i have learnt four chapters by your help . Award of best teacher goes to you
You make every topic so much less frustrating. Ty!
i just became a tutor for college algebra, but since i haven't took the course in six months-- i needed to remember everything so thank you so much!
God ❤bless you, you’ve helped me so much in my exams I had little time to prepare but have found it easy and I’m writing mathematics tomorrow
you taught me alot.i swear this man know everything
you sir are definitely gifted. the ease with which you explain topics like this is just mind blowing. thank you so much
We gettin outta pre calc with this one 😤 thank you so much bruh
Damn bro, now my life is blessed and I'm feeling overwhelmed
Thank you for being a wonderful substitute/teacher when needing help. I am not strong in the arithmetic area.
Literally thank you so much, I understood in 5 min, and my teacher couldn’t explain in it in a whole hour, thankss
still dont understand how guys like him can do a MUCH better job than most math teachers on this planet
This guy is single handedly taking me through Calculus 1 and now 2.
I'm doing this in alg 2 😧
Struggling with this equation just a week ago,tysm,u just explain it to me in just 2 min. that my teacher have failed to explain it to me lol ,keep it up
this is very helpful. Easy to get, easy to understand thank you!
