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.
