In mathematics, an exponential function is a function of the form

in which the input variable x occurs as an exponent. A function of the form ${\displaystyle f(x)=b^{x+c}}$, where ${\displaystyle c}$ is a constant, is also considered an exponential function and can be rewritten as ${\displaystyle f(x)=ab^{x}}$, with ${\displaystyle a=b^{c}}$.
