## Overview

**College Algebra: Concepts Through Functions, Third Edition**focuses on the fundamentals:

*preparation*for class,

*practice with*homework, and

*reviewing*of key concepts.

**With the Concepts Through Functions series, the Sullivans expose students to functions in the first chapter and maintain a continuous theme of functions throughout the text. This approach ensures students master basic skills and develop the conceptual understanding they need for the course, ultimately preparing students for future math courses as well.**

**ALERT: **Before you purchase, check with your instructor or review your course syllabus to ensure that you **select the correct ISBN**. Several versions of Pearson's MyLab & Mastering products exist for each title, including customized versions for individual schools, and registrations are not transferable. In addition, **you may need a CourseID**, provided by your instructor, to register for and use Pearson's MyLab & Mastering products.

__Packages__

Access codes for Pearson's MyLab & Mastering products may not be included when purchasing or renting from companies other than Pearson; check with the seller before completing your purchase.

__Used or rental books__

If you rent or purchase a used book with an access code, the access code may have been redeemed previously and you may have to purchase a new access code.

__Access codes__

Access codes that are purchased from sellers other than Pearson carry a higher risk of being either the wrong ISBN or a previously redeemed code. Check with the seller prior to purchase.
