STRATEGIES FOR SUCCESS: Learning aids are strategically placed throughout the text giving students guidance right when they needit. Chapter Openers discuss real-world situations that use mathematics from that chapter. Examples and exercises then relate back to the opening scenarios. Try This exercises after every example give students the opportunity to immediately try a problem that is just like the example and to check their work. Solutions to all Try This exercises are in Online Appendix B. Summaries of important concepts are included to help students clarify ideas that have multiple parts. Strategies contain general guidelines for accomplishing tasks and are useful for sharpening students’ problem-solving skills. Procedures are similar to Strategies, but are more specific and more algorithmic, designed to give students a step-by-step approach for problems. Function Galleries show families of functions and their graphs, helping students link the visual aspects with the mathematical properties. These appear throughout the text as appropriate and are also gathered together at the end of the text for easy reference. Graphing calculator discussions throughout the text support and enhance algebraic conclusions but are not used to arrive at those conclusions. These are optional and may be skipped, although students who do not use a graphing calculator may still benefit from the graphs and technology discussions.   MILESTONES ALONG THE WAY: Section exercises and review material include the following exercise types so students can practice and check their progress. Exercises are arranged by difficulty, from easy to challenging. Exercises that require a graphing calculator are marked with an icon and may be skipped. NEW! Data used in examples, exercises, and chapter openers has been updated to make this text relevant for today’s students. NEW! The number of fill-in-the-blank exercises has been increased to help students master the concepts. NEW! The exercise sets now contain new headings that group the exercises by type: Concepts, Skills, and Modeling. NEW! Exercise sets now contain QR codes which link the exercises to solution videos on the Web. NEW! Many new Outside the Box exercises have been added so that there are now two of them at the end of every section. For Thought exercises are ten true/false questions that review the basic concepts in the section, check student understanding before beginning the exercises, and offer opportunities for writing and discussion. Answers are included in the back of the student edition. Hints suggest ways of approaching a problem and give a starting point to solve the application problem. These are given for approximately five application problems in every exercise set. Cumulative review exercises at the end-of-section exercises are designed to keep current the skills learned in previous sections and chapters. These exercises are under the heading “Review.” Writing/Discussion and Cooperative Learning exercises deepen students’ understanding by giving them the opportunity to express mathematical ideas in writing and to their classmates during small group or team discussions. Outside the Box problems are designed to get students (and instructors) to do some mathematics just for fun and encourage students to apply creativity to unique problems.   TYING IT ALL TOGETHER: Chapter review material contains all of the following features to help students review
