A function is like a machine that takes an input and gives an output. Let's explore how we can graph, analyze, and create different types of functions.

This topic covers: - Evaluating functions - Domain & range of functions - Graphical features of functions - Average rate of change of functions - Function combination and composition - …

Functions assign a single output for each of their inputs. In this video, we see examples of various kinds of functions.

Functions are used in all sorts of real-world applications! For example, we use functions to model physical processes, like the motion of a car or the growth of a population.
