Addition of two functions

The video tutorial introduces the concept of functions and operations, focusing on function notation and the process of adding functions. It explains how to evaluate functions F(x) and G(x) and demonstrates the simplification of expressions involving these functions. The tutorial emphasizes understanding function notation and the steps involved in combining functions.

Can the expression F + g of X be simplified further? Why or why not?

What is the final expression for F + g of X?
