Evaluate the Composition of Two Functions

The video tutorial explains the composition of functions, focusing on evaluating G(F(X)). The instructor sets up an example, demonstrates the substitution of F(X) into G(X), and evaluates it with specific values. The roles of F(X) and G(X) are clarified, and the process is recapped for better understanding.

Explain the process of plugging F of X into G of X as mentioned in the text.

What is the significance of the input value for the G of X function?
