The video tutorial explains how to determine if two functions are inverses of each other. It introduces the concept of inverse functions and describes the method of using function composition to prove inverses. An example is provided to illustrate the process, showing that if the composition of two functions results in the identity function, they are inverses. The tutorial concludes by emphasizing the importance of satisfying both conditions for functions to be inverses.
