The range of the logarithmic function is -. Therefore it has an inverse function called the logarithmic function with base b. Expressed in terms of common logarithms this relationship is given by log mn log m log n.
The exponential function f xbx is one-to-one with domain and range 0.
First lets look at a graph of the log function with base e that is. Y logax only under the following conditions. X ay a 0 and a1. Displaystyle 3 2 9 32 9.
