Functions, Data, and Models: An Applied Approach to College Algebra 1st edition, by Sheldon P. Gordon and Florence S. Gordon, helps undergraduates use mathematics to make sense of the enormous amounts of data coming their way in today's Information Age. It can be used as a textbook in a college algebra course focusing on applications, in a quantitative literacy course, or in prerequisite courses for applied algebra or introductory statistics. Through partnership with the Mathematical Association of America, WebAssign is pleased to offer online question content along with interactive step-by-step tutorials for this title. All questions include links to the eBook for an integrated student experience.
