Functions And Change: A Modeling Approach To College Algebra
Functions And Change A Modeling Approach To College Algebra Author:Bruce Crauder, Benny Evans, Alan Noell Intended for students in a college algebra course who are not destined for an engineering-oriented calculus course, Functions and Change, A Modeling Approach to College Algebra, 2/e, has been revised with input from instructors across the curriculum: the sciences, business, economics, and political science. The text builds students' confi... more »dence in working with graphs, real data, and linear algebraic manipulations in these various disciplines. The authors' informal tone and exclusion of unnecessary technical terminology are well-suited to the non-science major to whom the book is targeted.Enhancing the text's practical approach are a thorough integration of graphing technology, high-quality, real-world applications, and an emphasis on modeling. Functions are introduced by the "Rule of Four"graphically, numerically, symbolically, and verbally. The text also features frequent use of data tables to display functions and an early introduction to realistic multivariate problems.
Functions and Change introduces concepts through applications (in context) instead of through theory. Many exercises are conceptual, requiring thought and interpretation, not just quantitative answers.
A wide diversity of relevant applications reveals mathematics as an integral part of nature, science, and society. In addition to offering more student appeal, the real-world context allows students to check their answers against their own intuition.
Key Idea boxes provide reinforcement by highlighting important concepts as they are presented.
In response to user feedback, Another Look review sections, accompanied by Enrichment Exercises, appear at the end of each section in the first six chapters, to enrich algebraic presentation and symbol manipulation and provide alternative treatments of the material.
Skill-Building exercises precede each exercise set in the text and additional exercises feature further practice in setting up formulas and a wider variety of non-science applications.
An icon has been added to help students identify ongoing problems, such as applications that are revisited in a more sophisticated way each time they appear.
Areas of new or enhanced content include the basic concept of a function; treatment of linear regression by hand calculations; exponential regression exercises; a section on logarithmic functions; a section on composition of functions and piecewise-defined functions; an expanded and self- contained section on quadratic functions; expanded coverage of polynomial and rational functions, including treatment of asymptotes; and expanded coverage of periodic functions and trigonometry.
