## Overview

**NOTE: **Before purchasing, check with your instructor to ensure you **select the correct ISBN. **Several versions of the MyLab™ and Mastering™ platforms exist for each title, and registrations are not transferable. To register for and use MyLab or Mastering, you may also need a** Course ID, **which your instructor will provide.

**Used books, rentals, and purchases made outside of Pearson**

If purchasing or renting from companies other than Pearson, the access codes for the MyLab platform may not be included, may be incorrect, or may be previously redeemed. Check with the seller before completing your purchase.

*For courses in precalculus.*

*This package includes MyLab Math.*

**Ties concepts together using a functions approach **

The ** Concepts Through Functions Series** introduces functions at the start of each text, and maintains a continuous theme by introducing/developing a new function in every chapter.

Known for their ability to connect with today’s students, acclaimed authors Sullivan and Sullivan focus on the fundamentals — **preparing for class, practice with homework, and reviewing key concepts — **encouraging students to master basic skills and develop the conceptual understanding needed for this and future courses. Graphing utility coverage is optional, and can be included at the discretion of each instructor based on course needs.

**Reach every student by pairing this text with MyLab Math**

MyLab™ Math is the teaching and learning platform that empowers instructors to reach *every* student. By combining trusted author content with digital tools and a flexible platform, MyLab personalizes the learning experience and improves results for each student.* *
