Prepare, practice, review

The proven approach of Sullivan and Sullivan focuses students on the fundamental skills of the course: prepare for class, practice with homework, and review the concepts. College Algebra Enhanced with Graphing Utilities fully integrates graphing utilities into topics, allowing students to explore mathematical concepts and encounter ideas usually studied in later courses. Many examples show solutions using algebra side by side with graphing techniques. In the 8th Edition, all exercises and examples in the text have been reviewed and updated as needed, and the authors have added new problem-solving and review features.

Hallmark features of this title

  • Just-in-time review begins all sections to prepare students for the topics ahead, with Preparing for This Section lists and Are You Prepared? Problems.
  • Section-level guidance helps develop problem-solving skills with Showcase Examples, highlighted Model It examples, Model It exercises, Now Work problems after most examples, Calculus icons and much more.
  • Assess Your Understanding appears after every section with a variety of problems for students to master needed skills.
  • Chapter Reviews offer a variety of convenient tools for reference and review:
    • You Should be Able To… objective lists and exercises by section; Review Exercises matched to learning objectives
    • Chapter Tests containing 15-20 problems each, and Cumulative Review problem sets.

New and updated features of this title

  • Need to Review? reminders now appear in the margin for key review topics, pointing students to the location of the review material in the textbook.
  • Graphing Utility Screen Captures: Desmos screen captures have been added in several instances, along with the TI-84 Plus CE screen captures. These updated screen captures provide alternative ways of visualizing concepts and making connections between equations, data, and graphs in full color.
  • New and enhanced Chapter Projects give students an up-to-the-minute experience. Many of the new projects require students  to research information online in order to solve problems.
  • Expanded Retain Your Knowledge problems: in most sections, problems preview skills students need to succeed in subsequent sections or in calculus (identified by a calculus icon). All answers to Retain Your Knowledge problems are in the back of the text and these problems are included in pre-built Enhanced Sample Assignments.
  • Challenge Problems now appear in the Applications and Extensions part of the section exercises, for students seeking problems with greater rigor. 
  • Key to Exercise Types helps users navigate the features of the exercise sets with a key at the bottom of the first page of each section's exercises.

Features of MyLab Math for the 8th Edition

  • Enhanced Sample Assignments are pre-made section-level assignments that address key concepts within the section and help keep previously learned skills fresh with Retain Your Knowledge questions.
  • Setup & Solve Exercises require students to show how they set up a problem as well as the solution. Both traditional and Setup & Solve versions of exercises within MyLab are provided.
  • Integrated Review content and assessments give students just the remediation they need, including Skills Check Quizzes by chapter; Personalized Skills Review Homework generated for each student based on the results of the Skills Check Quiz; Algebra Review eText, Exercises, Videos and Worksheets for additional help or for co-requisite courses.
  • Interactive Figures (formerly Guided Visualizations) are expanded to support teaching and learning. Created in GeoGebra by author Michael Sullivan III, the figures illustrate key concepts and allow manipulation. They have been designed to be used in lectures as well as by students independently.
  • Personal Inventory Assessments are a collection of online exercises designed to promote self-reflection and engagement in students. These 33 assessments include topics such as a Stress Management Assessment and Time Management Assessment.
