About this unit 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. Unit guides are here! …

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

Inputs and outputs of a function Learn Worked example: matching an input to a function's output (equation) Worked example: matching an input to a function's output (graph) Worked example: …

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.

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 …

Equations and functions are not the same thing, but they can be related in several ways. Watch Jesse Roe and Sal talk about the difference between equations and functions.

In this unit, we learn about functions, which are mathematical entities that assign unique outputs to given inputs. We'll evaluate, graph, analyze, and create various types of functions.

What do we mean by "shifting functions vertically?" Vertical shifting is similar to horizontal shifting, except we are moving the entire graph of the function up or down.

We've defined the functions for you, because we thought they'd be useful, and now it's up to you to decide what custom functions you want to use in your own programs.

The range of a function is the set of all possible outputs the function can produce. Some functions (like linear functions) can have a range of all real numbers, but lots of functions have a more …
