In this new edition of Precalculus, Seventh Edition, the authors encourage graphical, numerical, and algebraic modeling of functions as well as a focus on problem solving, conceptual understanding, and facility with technology. They responded to many helpful suggestions provided by students and teachers in order to create a book that is designed for instructors and written for students.

This book covers all of the needed chapters and concepts that are needed for Calculus. While most books show you complicated math expressions and equations to explain a rule, this book both explains it in an easy to understand way, and it shows it in simple and complex expressions and equations.

This textbook also has calculator views for all of the examples; this includes graphs and multi entry calculations. As a result, we believe that the changes made in this edition make this the most effective precalculus text available today.
