Graphing Logarithmic Functions and Domain and Range: Introduction

Earthquake

Logarithmic functions are extremely important in solving certain mathematical problems. Let’s go through one example of a logarithmic function. The magnitude of an earthquake is defined by the function . I is defined as the intensity of the earthquake and S is the intensity of a standard earthquake. Without the logarithmic function we would not be able to solve this problem. In this section we will take a closer look at the graph of logarithmic functions and their domain and range.
