What is a logarithm?
www.reed.eduGraphing with logarithms Another powerful use of logarithms comes in graphing. For example, exponential functions are tricky to compare visually. It’s hard to see what happens at small values and at large values at the same time because the function increases (or decreases) so quickly. To help with this, we sometimes plot the log of a function.
