CHAPTER 6: Exponential and Logarithmic Functions

This chapter introduces exponential and logarithmic functions. The exponential function is examined first as a function for which ratios of successive values of the function are constant, in contrast with linear functions for which amounts of change (first differences) are constant. By the end of this chapter, students should recognize exponential behavior and be able to model relationships with exponential and logarithmic functions. The Introductory Activity allows students to discover essential characteristics of both exponential and logarithmic behavior, which are then explained in the chapter.
