Exponential and logarithmic functions

Introduction

This chapter covers the algebra of functions and composite functions, and then logarithmic functions — including evaluating logarithms, the properties of logarithms, and the change-of-base formula.

Sections in this chapter

Exponential functions

Exponential functions and their graphs (growth and decay), and solving exponential equations by matching bases.

Logarithmic functions

Evaluating logarithms, properties of logarithms, compound interest, and changing the base of a logarithm.
