Graphical Approach to Precalculus with Limits, A, 7th Edition © 2019
John Hornsby | Margaret L. Lial | Gary K. Rockswold
A Graphical Approach to Precalculus with Limits, 7th Edition covers functions through a consistent 4-part process: 1) [See] examine the nature of the graph; 2) Solve a typical equation analytically and graphically; 3) Solve the related inequality analytically and graphically; 4) Apply analytic and graphical methods to solve an application. This proven approach fosters a deep visual and graphical understanding of math, solidifying a stronger connection to the mathematical world. Careful chapter layouts, exercises, review questions and chapter features give students a comprehensive roadmap for success in the course.
Hallmark features of this title
- Algebra Reviews refer students to finding additional help with important topics from algebra.
- Pointers include on-the-spot reminders and warnings about common pitfalls.
- Function Capsule boxes are a comprehensive, visual introduction to each class of function. Each includes traditional and calculator graphs and a calculator table of values, plus the domain, range and other specific information about the function.
- What Went Wrong? anticipates typical errors made when using graphing technology. Answers are included on the same page.
- Cautions and Notes warn of common errors and emphasize important ideas throughout.
- Looking Ahead to Calculus notes provide glimpses of how the algebraic topics being studied are used in calculus.
New and updated features of this title
- Unifying the Function feature appears after the introduction of each of the major classes of functions. Each instance of this new feature has a corresponding video and is assignable in MyLab Math® with accompanying assessment questions.
- Chapter 3 from the previous edition is now split into 2 chapters at reviewers' suggestion.
- Data has been updated throughout. Some new application topics include organic food sales, video-on-demand, active Twitter users, wearable technology, United States (U.S.) Snapchat users and online gaming revenue.
- Nearly 500 updated or new exercises have been added.
- Unifying the Function videos that were created by contributor Jessica Rockswold to spotlight the 4-step analytic process applied to each graph type: Analyzing the Graph, Solving an Equation, Solving an Inequality, and Solving an Application.
- Example Solution videos: 270 brand new videos, assigned in MyLab Math, are available to support students outside of the classroom and cover key topics in the text.
- GeoGebra Graphing Calculator and Tutorials: Students can now launch GeoGebra's online graphing calculator from within their MyLab Math course. The GeoGebra icon next to relevant examples in the etextbook launches a pop-up version.
- Users can also download the free app to use while completing assignments. Interactive, self-checking tutorials make it easy to get started with this dynamic tool. All resources are available within the Graphing Resources tab in MyLab Math.
- New Question types in MyLab Math include drag & drop, video assessment exercises, Guided Visualization questions, plus Setup and Solve that require a higher level of decision making.

John Hornsby
University of New Orleans
When John Hornsby enrolled as an undergraduate at Louisiana State University, he was uncertain whether he wanted to study mathematics, education or journalism. His ultimate decision was to become a teacher, but after 25 years of teaching at the high school and university levels and 15 years of writing mathematics textbooks, all 3 of his goals have been realized; his love for teaching and for mathematics is evident in his passion for working with students and fellow teachers as well. His specific professional interests are recreational mathematics, mathematics history and incorporating graphing calculators into the curriculum. John's personal life is busy as he devotes time to his family (wife Gwen, and sons Chris, Jack, and Josh). He has been a rabid baseball fan all his life. John's other hobbies include numismatics (the study of coins) and record collecting. He loves the music of the 1960s and has an extensive collection of the recorded works of Frankie Valli and the Four Seasons.
Margaret L. Lial
American River College
The late Marge Lial was always interested in math; it was her favorite subject in the first grade! Marge's intense desire to educate both her students and her inspired the writing of numerous best-selling textbooks. Marge, who received bachelor's and master's degrees from California State University at Sacramento, was most recently affiliated with American River College. An avid reader and traveler, her travel experiences often found their way into her books as applications, exercise sets, and feature sets. She was particularly interested in archeology, and trips to various digs and ruin sites produced fascinating problems for her textbooks, involving such topics as the building of Mayan pyramids and the acoustics of ancient ball courts in the Yucatan.
Gary K. Rockswold
Minnesota State University, Mankato
Gary Rockswold has been teaching mathematics for 33 years at all levels from 7th grade to graduate school, including junior high and high school students, talented youth, vocational, undergraduate and graduate students, and adult education classes. Now retired, he most recently served as professor of mathematics at Minnesota State University - Mankato. He graduated with majors in mathematics and physics from St. Olaf College in Northfield, Minnesota, where he was elected to Phi Beta Kappa. He received his Doctor of Philosophy (Ph.D.) in applied mathematics from Iowa State University. He has an interdisciplinary background and has also taught physical science, astronomy and computer science. Outside of mathematics, he enjoys spending time with his lovely wife and 2 children.
