Dynamic College Algebra

Dynamic College Algebra uses a modeling approach built around applications from technical fields such as semiconductor manufacturing and biotechnology. Each chapter begins with an engaging contextual problem that students explore in class or on their own via an Adobe Air simulation. Reflecting the realities of modern technical careers, Dynamic College Algebra integrates data analysis and spreadsheet technology throughout.

CHAPTER 3: Introduction to Functions

This chapter begins with the definition and properties of functions, which were introduced informally in Chapter 2. A detailed examination of linear functions is followed by a look at a basic catalog of simple function types, along with vertical transformations—shifts and stretches—of these functions. (Horizontal transformations are delayed until the study of exponential and other function types.) A section on creating other functions includes algebraic combinations, piecewise-defined functions, and composite and inverse functions. The chapter concludes with an introduction to matrices, with matrix addition and scalar multiplication paving the way for a return to linear functions in the guise of operations on matrices. The introductory activity allows students to examine essential characteristics of linear functions through a simulated data collection experiment in a chemical/biological context.
