How to graph a logarithmic function?
The graph of y = lobb(x - h) + k has the following characteristics
• The line x = h is a vertical asymptote.
• The domain is x > h, and the range is all real numbers.
• If b > 1, the graph moves up to the right. If 0 < b < 1, the graph moves down to the right.

Graph of Logarithmic Functions :
In science classes we will often find ourselves graphing logarithmic functions to describe situations such as motion or speed over time. When trying to identify these situations as those seen in graphing logarithmic functions, it is important to be able to recognize these graphs. It is also important to recognize graphs of exponential functions and their importance as the logarithmic inverse.
