LEARNING OBJECTIVES
By the end of this lesson, you will be able to:
- Identify the domain of a logarithmic function.
- Graph logarithmic functions.
In Graphs of Exponential Functions, we saw how creating a graphical representation of an exponential model gives us another layer of insight for predicting future events. How do logarithmic graphs give us insight into situations? Because every logarithmic function is the inverse function of an exponential function, we can think of every output on a logarithmic graph as the input for the corresponding inverse exponential equation. In other words, logarithms give the
