Polynomials are powerful tools for precalculus, as they can represent complex patterns and functions. In this unit, you will master the skills of working with polynomials, such as finding …

The first step is to find the answer of the function within the function. The second step is to input the answer of the function of the function in to the function on the outside.

This video is about composing functions, which is the process of building up a function by composing it from other functions. It explains how to evaluate the composition of functions …

From there, we'll move on to understanding continuity and discontinuity, and how the intermediate value theorem can help us reason about functions in these contexts.
