Evaluate the composition of two functions

The video tutorial guides students through evaluating the function G of 1, which involves calculating the square root of 1 plus 1. The result is then used to evaluate F of G of 1, which involves further simplification to arrive at the final result. The tutorial emphasizes understanding the process of plugging values into functions and simplifying expressions.
