# Ch 12: Inequalities and Absolute Values

Use these video lessons and quizzes help you learn about mathematical inequalities and absolute values. Find out how to evaluate, graph and solve absolute value expressions and functions here.

## Inequalities and Absolute Values - Chapter Summary

This chapter opens with an introduction to inequalities and their mathematical representations, such as those in algebraic, graphic, tabular and written form. You'll also learn about the domain and range of functions, or mathematical relations, including absolute values, radical, rational and polynomial, functions. At this point in the lesson, the instructor will show you how how to graph 1- and 2-variable inequalities.

In this chapter, you can also learn about absolute values, or the size of rational and irrational numbers, and find out how to evaluate and solve related expressions and problems. Additional instruction in graphing is covered, including absolute value functions, equations and inequalities. At the end of this chapter, you should be able to:

• Identify representations of mathematical functions related to inequalities and absolute values
• Discuss the limitations on the domains and ranges of mathematical functions
• Use a variety of methods to solve equations and inequalities involving functions, including algebraic methods, graphs and graphing calculators
• Model mathematical situations involving functions
• Evaluate the soundness of a solution

Our short and engaging video lessons are taught by professional instructors and are designed to expedite the learning process for complex topics. Along with the videos, you'll find transcripts with links to text lessons and additional details. When you finish the chapter, try the online self-assessment quiz to see how well you absorbed the information! If you find you need to revisit a key term or concept, you can use the video tags to review a specific part of the tutorial, without having to re-watch the entire presentation.
