This module provides tutorials and guidance on topics such as transitioning to college, online learning, time management and more. Additionally, there is content to help students with professional skills such as resume development and interview preparation.
• NEW! Reviewing Basic Concepts exercises are now assignable in MyMathLab. The exercise sets appear every two or three sections and allow students to review and check their understanding of the material in preceding sections.
• NEW! Graphing Functionality allows students to graph 3-point cubic, 4-point quadratic and transformation graphs within MyMathLab exercises.

Build students’ analytical skills: The four-step analytical process is the foundation of the Hornsby approach. In addition, the authors build sound pedagogy to support analytical thinking. Chapter layouts, exercises, review questions and chapter features offer a comprehensive roadmap for students to follow for a successful understanding of algebra and trigonometry.

• NEW! Chapter tests have been revised to better reflect the content that was covered.
• NEW! More examples and exercises have been added to better prepare students for analytic skills.
• NEW! Exercise sets have been revised so that odd and even exercises are paired appropriately.
• NEW! Algebra Reviews occur in the margin of the text and provide “just in time” review by referring students to where they can receive additional help with important topics from algebra.
• Pointers direct students to comments that include on-the-spot reminders and warnings about common pitfalls.
• Chapter openers provide a Chapter Outline and a motivating application topic that is tied to the chapter content.
• Enhanced examples have replaced many examples in this edition. All solutions have been carefully polished to incorporate more side comments.
• Function Capsule boxes offer a comprehensive, visual introduction to each class of function and serve as an excellent resource for reference and review. Each capsule includes traditional and calculator graphs and a calculator table of values, as well as the domain, range, and other specific information about the function. Abbreviated versions of function capsules are provided on the inside back cover of the text.
• The What Went Wrong? feature anticipates typical errors that students make when using graphing technology and provides an avenue for instructors to highlight and discuss such errors. Answers are included on the same page as the “What Went Wrong?” boxes.
• Cautions and Notes warn students of common errors and emphasize important ideas throughout the exposition.
• Exercise sets include hundreds of new and revised exercises that provide students with ample opportunities to practice, apply, connect, and extend concepts and skills. Exercises include writing exercises as well as multiple-choice, matching, true/ false, and completion problems. Exercises marked Concept Check focus on mathematical thinking and conceptual understanding, while those marked Checking Analytic Skills are intended for students to solve without the use of a calculator. Real data has been updated throughout.
• Looking Ahead to Calculus are margin notes that provide glimpses of how the algebraic topics currently being studied are used in calculus.
• Relating Concepts exercises appear in select exercise sets. They tie together topics and highlight relationships among various concepts and skills. All answers to these problems appear in the answer section at the back of the student book.
• Reviewing Basic Concepts sets of exercises appear every two or three sections and allow students to review and check their understanding of the material in preceding sections. All answers to these problems are included in the answer section at the back of the student book.
• Chapter review material appears in each end-of-chapter Summary and features a section-by-section list of Key Terms and Symbols, in addition to Key Concepts. A comprehensive set of Chapter Review Exercises and a Chapter Test are also included.

The visualizations throughout the text have been enhanced to increase students’ comprehension of core algebra and trigonometry concepts.

• NEW! Data has been updated to increase student interest in mathematics. Some new application topics include half-life of a Twitter^™ link, iPads^®, social networks, accuracy of professional golfers, and smart phone demographics.
• NEW! The text has more titles on graphs, captions, pointers (bubbles), color, and side comments to increase clarity and understanding for students.
• Figures and photos appeal to today’s students who are more visually oriented than ever. As a result, more figures, diagrams, tables, and graphs, including the “hand-drawn” style of graphs are provided whenever possible. Photos accompany applications in examples and exercises.
