Function Operations and Composition

This video tutorial covers operations with functions, including addition, subtraction, multiplication, division, and composition. It explains how to perform these operations by substituting and simplifying functions, focusing on exponent rules and the concept of like terms. The tutorial also introduces function composition, demonstrating how to plug one function into another and simplify the result. The video aims to provide a comprehensive understanding of these operations, equipping students with the skills to handle various function-related problems.

What operations can be performed with functions as introduced in the video?
