Lesson Summary:

In this lesson, we learn how to prove that two functions are inverses of each other. The key is to use composition - plug one function into the other and evaluate. If the result is x both ways, then the functions are inverses. The transcript shows an example of proving the inverse functions f(x) and g(x), with step-by-step explanation and cancellation of terms. By understanding this process, we can confidently prove the inverse of any pair of functions.

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
