Exponential Functions

An exponential function is a function of the form $f\left(x\right)\=c\cdot a^x$, where $a\>0$ and $c\ne 0$ are constants. It is common to exclude the case $a\=1$, as then the function reduces to just the constant function $f\left(x\right)\=c$.

The Exponential Function

The exponential function is the function $f\left(x\right)\={{\ⅇ}^x}^{}$, where $\ⅇ \=2.718281828..\.$ . This function is also often written as $f\left(x\right)\=\exp \left(x\right)$, particularly when the argument, $x$, is a large or complicated expression.
