In this section we will introduce logarithm functions we give the basic properties and graphs of logarithm functions in addition we discuss how to evaluate some basic logarithms including the use of the change of base formula we will also discuss the common logarithm log x and the natural logarithm ln x.

The most common exponential and logarithm functions in a calculus course are the natural exponential function bf e x and the natural logarithm function ln left x right we will take a more general approach however and look at the general exponential and logarithm function.

Bacterial growth curve and its significance a population growth curve for any particular species of bacterium may be determined by growing a pure culture of the organism in a liquid medium at a constant temperature.
