Evaluating the Composition of Two Functions, Linear and Quadratic

The video tutorial explains the process of function composition, specifically focusing on substituting and calculating values within functions. It demonstrates how to substitute G of X with G of -5, calculate its value, and then replace it in another function, H of X, to solve for H of -1. The tutorial concludes with a brief discussion on homework and the importance of following the step-by-step process.
