How To Find The Inverse of a Function

This algebra 2 and precalculus video tutorial explains how to find the inverse of a function using a very simple process. First, replace f(x) with y. Next, switch x with y. Finally, solve for the y variable and that's it. This video contains examples and practice problems that include fractions, radicals, square roots, cube roots, linear functions, and cubic functions.

you just explained in 2 minutes what my math teacher failed to in 2 hours.. thank you

[theoddball]

after watching this video, my skin is clear, life is good, and I'm feeling blessed.

[Kekzuu]

can you teach my algebra teacher how to teach please

[JFurk]

literally having my Finals math test in about 30mins, you just explained this quite easily and i actually understood it quickly.

[colbyl]

In 11 minutes, you just explained what i've struggled the whole morning to understand. Keep up the great work! :)

His voice is 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

Bro, you are a blessing in this world, can't express how much we love you. Long live Organic Chemistry Tutor

[aabidsadik]

Struggled with these kinds of equations for 2 years, 2 YEARS. Thanks for making this explanation easy to follow and nicely placed out. 👍

[stormshade]

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.

[hangersan]

The dude teaches like my former math teacher, who made me feel like a math genius with his teaching method.

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.

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😊

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!

[donnelly]

Amazing how proper instruction can actually help one understand the subject matter.

[ycgkrkk]

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 .

[ObaydFox]

DANG IT! I was watching then Karlie Kloss came on saying how to make a website with wix! Appart from that, great vid!!!

[jertmasangkay]

So all of us here have bad math teacher huh

[omarmohammd]

there is just a thing with your voice. It sounds so refreshing and chill. Makes me acc like math. You explained everything so well
