Introduction
Introduction
In our study of functions, the previous chapter explored exponential functions. However, every function needs an inverse function (an undo button). The inverse function to exponential is the logarithmic function.

Recalling the graphs of exponential functions, logarithms are the index (in red) that gives us a specific power (in blue). Move the Blue Dot to shift the power or the Blue Slider to change the base of the graph.
