Section Exercises are organized by question type, and generally appear in the following order:
-
Verbal questions assess conceptual understanding of key terms and concepts.
-
Algebraic problems require students to apply algebraic manipulations demonstrated in the section.
-
Graphical problems assess students’ ability to interpret or produce a graph.
-
Numeric problems require the student perform calculations or computations.
-
Technology problems encourage exploration through use of a graphing utility, either to visualize or verify algebraic results or to solve problems via an alternative to the methods demonstrated in the section.
-
Extensions pose problems more challenging than the Examples demonstrated in the section. They require students to synthesize multiple learning objectives or apply critical thinking to solve complex problems.
-
Real-World Applications present realistic problem scenarios from fields such as physics, geology, biology, finance, and the social sciences.
Chapter review features
Each chapter concludes with a review of the most important takeaways, as well as additional practice problems that students can use to prepare for exams.
-
Key Terms provides a formal definition for each bold-faced term in the chapter.
-
Key Equations presents a compilation of formulas, theorems, and standard-form equations.
-
Key Concepts summarizes the most important ideas introduced in each section, linking back to the relevant Example(s) in case students need to review.
-
Chapter Review Exercises include 40-80 practice problems that recall the most important concepts from each section.
-
Practice Test includes 25-50 problems assessing the most important learning objectives from the chapter. Note that the practice test is not organized by section, and may be more heavily weighted toward cumulative objectives as opposed to the foundational objectives covered in the opening sections.
-
Answer Key includes the answers to all Try It exercises and every other exercise from the Section Exercises, Chapter Review Exercises, and Practice Test.
