Identify the domain of a logarithmic function Before working with graphs, we will take a look at the domain (the set of input values) for which the logarithmic function is defined.

In this section, you will learn how to find domain and range of logarithmic functions. The table shown below gives the domain and range of different logarithmic functions.

Nov 16, 2025 · The domain of a log function consists of all real numbers for which the argument of the logarithm is strictly positive. In essence, how to find the domain of a log function? involves solving an …

However, in general settings, the logarithm tends to be a multi-valued function. For example, the complex logarithm is the multi-valued inverse of the complex exponential function. Similarly, the …
