Description

College Algebra in Context, Fourth Edition is ideal for students majoring in business, social sciences, and life sciences. The authors use modeling, applications, and real-data problems to develop skills, giving students the practice they need to become adept problem solvers in their future courses and careers.

 

This revision maintains the authors’ focus on applying math in the real world through updated real-data applications. Features such as Group Activities and Extended Applications promote collaborative learning, improve communication and research skills, and foster critical thinking. MyMathLab has increased exercise coverage, pre-built sample assignments, and Ready-to-Go course options that make it easier to get started with online homework.

Features

  • Real-Data Applications, 50% of which are new or updated in this edition, keep the text up-to-date with recent economic and financial changes. Applications are the hallmark feature of this text, written to prepare students to solve problems in their future courses and varied careers.
    • Each section begins with a motivational problem that presents a real-life setting. The problem is solved after the necessary skills are presented in that section.
    • Special business and finance models are included to demonstrate the applications of functions to the business world.
  • Group Activities and Extended Applications encourage communication skills and collaborative learning by asking students to apply their knowledge in creative ways.
  • Chapter openers begin with a brief application that shows how the upcoming material relates to the real world. A small grid lists a few of the applications that students will see in each section, to motivate them to read the text.
  • The Algebra Toolbox at the beginning of every chapter provides a “just in time” review of the algebra needed to learn upcoming material. Each Algebra Toolbox begins with a list of Key Concepts, just like the sections in the book, to make this tool even more useful for students.
  • Key Concepts are outlined at the beginning of every section. These lists are consistent with the order and organization of the material in the chapter reviews, providing a helpful cross-reference for exam preparation.
  • Skills Check problems precede the exercise sets, allowing students to quickly check if they have read and understood all the concepts needed to complete their homework.
  • Exercise sets are designed to test student comprehension by incorporating the algebraic skills covered in the Skills Check with the application problems they will encounter in the real world.
  • Chapter review material includes a wealth of material to help students study efficiently.
    • A chapter summary and grid outline Key Concepts and Formulas, which are organized by section and point back to the Key Concepts list at the beginning of each section.
    • Skills Check problems and the exercise sets test students’ comprehension of the material in the chapter.
  • Highlights of the MyMathLab® course:
    • NEW! Ready-to-Go MyMathLab courses are pre-built MyMathLab courses that make the start-up time for building your course quick and easy.
    • NEW! Author-designated sample homework problems are available in MyMathLab to make your start-up time efficient.
    • Narrated Example Videos have been updated to reflect new content and current real data.
    • NEW! Introductory Videos contain a brief overview of the topics covered in each section and highlight objectives and key concepts. These videos give context to the Narrated Example videos.

 

New to this Edition

  • Real-data applications, examples, and exercises have been updated, keeping this text’s content up-to-date with economic and financial changes in recent years.
  • Updated Section Previews prepare students for the section ahead, with examples listed in the same order in which they will appear in the section.
  • Additional Skills Check problems ensure that students have sufficient practice with every type of skill.
  • Additional modeling questions throughout the text have students do more decision making and critical thinking.
  • Appendix B has been expanded to include instructions for both Excel® 2003 and Excel® 2010. Whenever a new technology procedure is introduced in the text, references point students to Appendices A and B for calculator and Excel instructions.
  • Content updates are focused on improving the exposition and organization of the book.
    • Chapter 4 Toolbox has been revised to contain a library of functions.
    • The discussion of one-to-one functions has been moved to section 4.3 (Inverse Functions).
    • Section 1.1 (Functions and Models) now contains an expanded discussion of mathematical models.
    • Section 1.3 (Linear Functions) contains a more complete introduction to revenue, cost, and profit functions.
    • Section 2.1 (Algebraic and Graphical Solutions of Linear Equations) contains an expanded discussion of direct variation.
    • Chapter 3 (formerly entitled “Quadratic and Other Nonlinear Functions”) now has increased emphasis on power functions, and its title has been updated to reflect this change. This chapter also contains additional discussion of graphing and solving equations with Excel.
    • Section 3.1 (Quadratic Functions; Parabolas) contains an expanded discussion of graphing quadratic functions. This section has also been reorganized to complete the discussion of exponential functions before discussing exponential growth and decay.
    • Section 3.3 (Piece-wise-Defined and Power Functions) now contains discussions of direct variation as an nth power and inverse variation.
    • Section 4.2 (Combining Functions; Composite Functions) now includes a more complete introduction to the average cost function.
