Composite Functions

The video tutorial covers the journey from basic functions to composite functions. It begins with an introduction to functions as input-output machines, explains inverse functions and their notation, and then delves into composite functions, which combine multiple functions into one. The tutorial provides practical examples, such as calculating oxygen concentration based on altitude, and demonstrates solving composite functions both manually and algebraically. The importance of function order and notation is emphasized throughout.
