An exponential function has the form $\quad f(x)=b^{x},$
where b is called the base, and is a positive number, $ b\neq 1.$
If the base is $ e $ (the natural base), it is called the natural exponential function.
The number $e$ is defined as the value that $(1+\displaystyle \frac{1}{n})^{n}$ approaches as n gets very large.
An approximation: $ e\approx 2.718281827$
