The Natural Base (e)

The natural base is a constant defined as:

The natural base is often used to model continuous growth and continuous decay.

Natural Base Exponential Function

An exponential function with base e is a natural base exponential function.

Natural Logarithm

The logarithm with base e is called the natural logarithm. You may see it written two different ways:
