Master Determining if a function has an inverse from a graph and then graphing the inverse

The video tutorial explains how to determine if a function has an inverse by using the vertical and horizontal line tests. It discusses the concept of one-to-one functions and how to reflect graphs across the X=Y line to find inverses. The tutorial provides examples of functions with and without inverses and emphasizes the importance of these tests in identifying inverses graphically.
