About This Lesson
In this video series I will show you how to find the inverse of a function by graphing and algebraically. With a graph two inverses are related to each other as the reflection over the y=x line. Algebraically to find the inverse we need to follow the algorithm for inverses. We first need to replace our function notation with a variable most commonly used is y. We then swap our input(x)and output(y) variables and then solve for y. We then replace the y for inverse function notation. http://www.freemathvideos.com
