Introduction to Functions and Composite Functions

The video tutorial explains functions as machines that process inputs to produce outputs. It covers the concept of inverse functions, which reverse the process of the original function, and composite functions, which combine multiple functions to form a new one. The tutorial uses algebraic expressions to demonstrate these concepts, emphasizing the importance of understanding function notation and operations.
