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.

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) …

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 …

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

Not all functions have inverses. Those who do are called "invertible." Learn how we can tell whether a function is invertible or not.

This topic covers: - Intercepts of linear equations/functions - Slope of linear equations/functions - Slope-intercept, point-slope, & standard forms - Graphing linear equations/functions - Writing linear …

Reviewing graphs of single-variable functions Graphs are, by far, the most familiar way to visualize functions for most students. Before generalizing to multivariable functions, let's quickly review how …

Let's extend trigonometric ratios sine, cosine, and tangent into functions that are defined for all real numbers. You might be surprised at how we can use the behavior of those functions to model real …
