Composing Two Quadratic Functions

The video tutorial explains the composition of two functions, F of X and G of X, and how to evaluate G of F of X. It covers the substitution process, multiplication of expressions using the FOIL or box method, and simplification to reach the final answer. The tutorial emphasizes the importance of correctly applying mathematical operations and provides a step-by-step guide to solving the problem.
