Ex 1: Find the Inverse of a Function

This video provides two examples of how to determine the inverse function of a one-to-one function. A graph is used to verify the inverse function was found correctly.

I truly hope you recognize what a positive and monumental impact you've had on struggling students throughout the years. You're a Godsend and we all thank you.

for those confused, he simply rationalized the denominator, which means getting rid of the radical by multiplying the top and bottom by cube root 2 so he can get an 8 in the denominator which simplifies perfectly to 2 because cube root of 8 is 2. remember to multiply radicals you have to have like radicals.

I can’t understand u sometimes miss steps in your videos

First of all, I appreciate all of your videos. Now with the content of it, I just want to clarify when you rationalized the denominator as well as nominator. You added 2 next to X, and I just wonder why? Can you give me your reason. Thanks in advance!

you lost me on the cube root of 4 being 2

[dreaxox]

If I have a different exponent instead of 3 like in the second example do I still cube root?

[littlebearkings]

What if I have the 5th root of 4? How do I solve that?

MyopenMath didn't didnt like the final answer but it did like 3^Sqrt(x-4)/4=y
