Evaluate the Composition of a Radical and Rational Function

The video tutorial explains the concept of function composition, specifically focusing on evaluating F of G of four. It starts by simplifying the expression and calculating G of four using the square root function. The tutorial then demonstrates how to replace G of four with two, leading to the evaluation of F of two. The process involves substituting values and performing basic arithmetic operations to find the final result.
