Understanding Composite Functions

The video tutorial explains how to determine composite functions F of G of X and G of F of X. It begins by rewriting the functions in a more manageable form and then walks through the process of substituting and simplifying each function. The tutorial provides a step-by-step guide to calculating both composite functions, highlighting key simplifications and transformations. The video concludes with a summary of the results for both F of G of X and G of F of X.

What is the purpose of rewriting composite functions in a different form?

• To eliminate the need for substitution

• To change the function's output

• To simplify the process of finding the composite function

• To make them more complex
