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' confidence in working with graphs, real data, and linear algebraic manipulations in these various disciplines. Enhancing the text's practical approach are a thorough integration of graphing technology, high-quality, real-world applications, and an emphasis on modeling.
