Explore the concept of absolute value in terms of distances traveled. This video focuses on a real world application of absolute value and visualizes the problem by graphing points on coordinate plane.

A discussion of how to solve absolute value problems. The lesson goes into detail about the graphs of absolute value problems and how the graph is related to the numeric solution. Includes problems along with interactive widgets.

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

Here is a site that clearly and thoroughly explains the graphs of the major mathematical functions. There are example problems solved, problems for the student to attempt, and answers to the student problems. Point this site out to...

Straightforward explanations on how to solve inequalities. Includes linear inequalities, double inequalities, absolute value inequalities, polynomial inequalities, and rational inequalities.

In this section we will do a very quick review of many of the most common functions and their graphs that typically show up in a Calculus class.

Given the graph of a step function, find the function's outputs for given specific inputs. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
