This section illustrates how logarithm functions can be graphed, and for what values a logarithmic function is defined. To graph a logarithmic function y = logb(x), it is easiest to convert the equation to its exponential form, x = by.

A logarithmic function involves logarithms. Its basic form is f(x) = log x or ln x. Learn about the conversion of an exponential function to a logarithmic function, know about natural and common logarithms, and check the properties of logarithms.
What are logarithmic functions with equation. Learn graphing them and finding domain, range, and asymptotes with examples
Define and evaluate logarithms. Identify the common and natural logarithm. Sketch the graph of logarithmic functions. We begin with the exponential function defined by f(x) = 2x and note that it passes the horizontal line test. Therefore it is one-to-one and has an inverse.
Graphing a logarithmic function can be done by examining the exponential function graph and then swapping x and y. The graph of an exponential function f (x) = b x or y = b x contains the following features: The domain of an exponential function is real numbers (-infinity, infinity).
This algebra video tutorial explains how to graph logarithmic functions using transformations and a data table. It explains how to identify the vertical asymptote as well as the domain and...
In this section we will discuss the values for which a logarithmic function is defined, and then turn our attention to graphing the family of logarithmic functions.
In this section, we will discuss the values for which a logarithmic function is defined and then turn our attention to graphing the family of logarithmic functions. Before working with graphs, we will take a look at the domain (the set of input values) for which the logarithmic function is defined.
To graph a log function, start with the fact that logs *are* exponents. For example, since 2³=8, then log₂(8)=3, and (8,3) is a point on the graph.
