F. Logarithmic Functions
The TI-86 will graph the natural logarithm, y=ln x, and the common logarithm, y=log x. However, graphing functions in other bases requires use of the Change of Base Property.
1. Natural Logarithms and Common Logarithms
These functions can be entered directly. Parentheses must be placed around the function terms.
Example: Enter the functions shown.

2. Other Bases
Functions such as
cannot be entered directly, so you will have to use the Change of Base Property to rewrite the function as
.
