The logic of nested operations: mastering composite functions

Evaluating composite functions | Mathematics III | High School Math | Khan Academy · 4:09 · Video: Khan Academy · Watch at the source

In short: Understanding how different mathematical rules interact is key to mastering algebra. This tutorial demonstrates how to evaluate composite functions by systematically processing inputs through multiple layers of operations.

The video provides a step-by-step walkthrough on evaluating the composition of two functions, specifically (h ∘ g)(-6). It guides viewers through the process of first finding the output of the inner function, g(x), and then using that result as the input for the outer function, h(y).

By breaking down complex expressions into these sequential steps, the lesson clarifies the foundational logic used in higher-level mathematics.
