What are rational functions? How do we plot them? What is their domain and range? Let's find out. We break down the definition of the function given in set-builder form and plot the graph by connecting …

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.

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

Using function notation to describe rules (part 1) Learn Worked example: Evaluating functions from equation

Create functions that match one variable to the other in a two-variable equation. Functions are written using function notation.

Shift functions horizontally and vertically, and practice the relationship between the graphical and the algebraic representations of those shifts.

We can compose functions by making the output of one function the input of another one. This simple-yet-rich idea opens up a world of fascinating applications. Inverse functions undo each other when …

This unit explores how functions interact through composition and inversion. You'll learn how to find and represent inverse functions, restrict domains to ensure functionality, and use compositions to verify …
