Master Determine if two function are inverses of each other formally ex 1

The video tutorial explains how to determine if two functions are inverses by using composition. It demonstrates that if the composition of two functions results in the identity function, they are inverses. The tutorial provides three examples: two where functions are inverses and one where they are not.

How do you confirm that G of F of X works as well when proving functions are inverses?

What is an example of two functions that are not inverses, and why?

Summarize the steps needed to formally prove that two functions are inverses.
