Summary

Designed for a “prep” course for college algebra or an alternative course to college algebra for students seeking a terminal math course to fulfill a math requirement.
This text provides comprehensive coverage of Intermediate Algebra plus coverage of polynomial and rational functions, sequences, probability and mathematical induction to prepare students for college algebra, precalculus and other “service” math courses. The material is presented in an interesting and inviting format that utilizes “real world” data and encourages modeling, critical thinking and problem solving.

Features


NEW—Integration of AMATYC and NCTM Standards

  • Over 50 % of the applications and many of the examples have been extensively researched and rewritten to incorporate current, real-world data drawn from familiar sources such as the 1995 Statistical Abstract of the U.S. published by the Census bureau.
  • Graphing is introduced and integrated earlier, starting in Section 1.3.
  • Functions are introduced in Chapter 2 and emphasized throughout in Chapters 3, 4, 5, 7, and 8.
NEW—Text organization reflects an emphasis on problem solving. Chapter 1 is now “Algebra and Problem Solving,” Section 3.2 includes“Problem Solving and Modeling using Systems of Equations,” and Section 4.7 explores “Polynomial Equations and Problem Solving.”
NEW—Using Technology, Study Tips, and Discover for Yourself features have been added as pedagogical enrichment to encourage student success. Study Tips in particular, make mathematical content more accessible.
NEW—Chapter Projects, extended one-page applications, conclude each chapter. Some activities feature related websites (available to students via the Prentice Hall/Blitzer website) for student research and exploration.
NEW—Optional Graphing utility opportunities have been added in appropriate sections and exercise sets. These sections, examples and exercises feature explorations, many with real screen grabs from the TI-83.
NEW—Chapter Tests are included at the end of each chapter for more review and reinforcement. FEATURES
An abundance of interesting and varied exercises are included (50% have been rewritten) to appeal to the modern (often non-traditional) student. The exercises, examples and writing style has been carefully and extensively reviewed and revised to better meet the level of student taking a developmental math course.
Modeling is introduced in Chapter 1 and emphasized throughout.
Real world sourced data, interpretation of data and visualization is fully integrated.
  • The use of fine art, historical notes and interdisciplinary connections are introduced in the context and applicability of algebra.
