Function composition becomes much easier when you think of functions as machines.
In this video, you’ll learn how to solve function composition problems by “feeding” the output of one function into another function machine. Instead of memorizing formulas, you’ll learn a simple visual process that helps you understand what function composition is actually doing.
In this lesson you’ll learn:
• What function composition means
• How function machines model composition
• Why f(g(x)) means “do g first, then f”
• How to evaluate composed functions
• How to simplify function compositions
• Common mistakes students make
By the end of the lesson, you’ll understand why function composition works and how to solve composition problems with confidence.
