- 7.1: Composition and Inverse Functions
- In mathematics, it is often the case that the result of one function is evaluated by applying a second function.

- 7.2: Exponential Functions and Their Graphs
- In this section we explore functions with a constant base and variable exponents.

- 7.3: Logarithmic Functions and Their Graphs
- The logarithm is actually the exponent to which the base is raised to obtain its argument.

- 7.4: Properties of the Logarithm
- We can use the properties of the logarithm to expand logarithmic expressions using sums, differences, and coefficients. A logarithmic expression is completely expanded when the properties of the logarithm can no further be applied.

- 7.5: Solving Exponential and Logarithmic Equations
- In this section we describe two methods for solving exponential equations.
