**The Sullivan’s** time-tested approach focuses students on the fundamental skills they need for the course: *preparing *for class, *practicing *with homework, and *reviewing* the concepts. The **Enhanced with Graphing Utilities Series** has evolved to meet today’s course needs by integrating the usage of graphing calculators, active-learning, and technology in new ways to help students be successful in their course, as well as in their future endeavors.

In the Seventh Edition, there are several new features that appear in both the text and MyMathLab. **Retain Your Knowledge** problems offer the type of “final exam material” that students can use to maintain their skills throughout each chapter.

We offer sample solutions for Precalculus Enhanced with Graphing Utilities (7th Edition) homework problems. See examples below:
