Master Determine if two functions are inverses of each other formally ex 2

The video tutorial explains how to determine if two functions are inverses by composing them in both orders and simplifying to see if the result is the identity function, X. It provides multiple examples, demonstrating the process of plugging one function into another, simplifying, and checking if the result is X. The tutorial also highlights common mistakes and clarifies the importance of verifying both compositions to confirm inverse relationships.
