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: two …

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.

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! Power up your …

Many functions are equations. But, they don't have to be. If you have a set of ordered pairs where each x-value relates to only one y-value, then you have a function. For example: { (2,5); (3,8); (5,7); (-3,6) …

Rearranging to solve for the variable you want to measure, you get a function (as long as there's not multiple outputs for any input)! Functions involve anything with an independent and dependent …
