Learn about the vertical line test for functions by trying to connect points in the plane to build a function. When you have connected all of the points, you will be told if your graph is a valid graph of a function.

This site from The Franklin Institute explores how to make a simple graph using a spreadsheet to portray survey data. It also gives a set of interesting sports-related web sites so that students can get statistical inforamtion.

A survey of math graphing techniques includes horizontal and vertical shifts, stretching, lines of symmetry, even and odd functions, and absolute value functions.

This section explores the process for finding inverses of functions, and then proving the function and its inverse algebraically. Additionally, it explores how the graphs of functions and their inverses compare to each other, and it...

This site explains what a linear equation is, general forms of linear equations, how to graph a line using the method of plotting points. The site also details how to find points on the line given the equation, information about the...

An introductory look at the definition of an inverse function, the notation used for inverse functions, and tests used to determine whether a function will have an inverse. Several examples are provided for the student to scroll through...
