Finding the Composition of Two Functions

The video tutorial explains the concept of function composition, focusing on evaluating F of G of X and G of F of X. It covers the process of plugging one function into another and discusses simplification rules, especially concerning radicals. The tutorial emphasizes that operations like addition and subtraction cannot separate radicals, and highlights the cancellation of square roots and squares. The video concludes with a summary of key points on function composition.
