**Michael 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 calculator, active-learning, and technology in new ways to help students be successful in their course, as well as in their future endeavors.

In the **Sixth Edition**, new worksheets in MyMathLab—developed from the authors’ experience in the classroom—provide mixed review for students who having trouble reconciling various topics, and also give students an opportunity to show their work. The “Are You Prepared?” section openers focus on students mastering the prerequisite material before beginning a new topic, and for the first time, those exercises are assignable in MyMathLab. Concept and Vocabulary exercises are also now assignable in MyMathLab as reading quizzes.

Graphing Utility to Create Tables In addition to graphing equations, graphing utilities can also be used to create a table of values that satisfy the equation. This feature is especially useful in determining an appropriate viewing window when graphing an equation. EX AM PL E 1 1 Creating a Table Using a Graphing Utility Create a table that displays the points on the graph of 6x2 + 3y = 36 for x = -3, -2, -1, 0, 1, 2, and 3. Step-by-Step Solution Step 1 Solve the equation for y in terms of x.
