In this lesson on logarithms, the focus is on graphing logarithmic functions. The first step is to rewrite the function as y = log base 2 of x, and then rewrite it as an exponential function, which is 2 to the y = x. By making a table of ordered pairs and plotting them on a graph, the unique shape of a logarithmic function can be seen. Additionally, by understanding the basic shapes of both exponential and logarithmic functions, it becomes easier to graph more complex functions.
In this video, we graph logarithmic equations.
