Function Composition and Evaluation

The video tutorial introduces three function definitions: F, G, and H. It explains the concept of composing functions, which involves building a function by nesting other functions. The tutorial provides step-by-step evaluations of F(G(2)), F(H(2)), and a triple composition example H(G(F(2))). These examples help illustrate how to evaluate compositions of functions.
