Chapter 8: We put more emphasis on solving absolute value inequalities symbolically. A new objective that more fully discusses the concept of a relation was inserted before the definition of a function, and exercises were added that give students practice differentiating between relations and functions.

Also, a new objective on piecewise-defined functions was added in Section 8. Chapter 9: New exercises that ask students to represent simple social networks with matrices were added to this chapter. Chapter The coverage of using zeros to write the formula for a function was expanded in Sections Chapter A new graphical description for deriving the formula to find the vertex of a parabola is now included. Also, a real-world example was added to highlight a common situation in which a quadratic equation might have zero, one, or two solutions.

This chapter additionally includes increased coverage of complex solutions to quadratic equations. Chapter A discussion connecting social network posts with half-life and exponential decay is now included to give students a relevant and accessible example of this important concept.

At the request of reviewers, we expanded the coverage of changing between exponential and logarithmic forms of equations. Chapter New exercises involving the equation of a circle were added. Chapter In this final chapter, the coverage of writing a formula for a sequence from given terms of the sequence was increased. Table of Contents 1. Introduction to Algebra 1.

Objective-level video clips have also been added to the MyMathLab course for every objective, with accompanying icons throughout the text. Updated and expanded! It also provides additional practice, vocabulary, and skill reinforcement. Career Explorations have been integrated throughout the text and MyMathLab course in an interactive format that contextualizes the math to engage students and get them thinking about future career possibilities.

Career Exploration Problems foster active learning and better understanding of the math concepts, and are assignable in MyMathLab. Use Math to Save Money Animations expand on a favorite feature from the text, allowing students to put the math they just learned into context.

They are included in the MyMathLab course. Many also include assignable Use Math to Save Money Exercises in MyMathLab that instructors can assign to ensure students watched the animation and understood the concepts.
