How to find and graph the inverse of a linear function

The video tutorial explains how to find the inverse of a function using an algorithm. It begins by replacing the function with y, swapping variables, and solving for y. The tutorial demonstrates undoing multiplication by a fraction using the reciprocal. It then shows how to graph the original function and its inverse, emphasizing the reflection about the identity line. The lesson concludes with a discussion on labeling the functions and their inverses.
