The exponential function is the function $f(x) = e^x$, exponentiation by e. It is a very important function in analysis, both real and complex.


Exponential equations are in one of three forms. $f\left( x \right) = ab^x$, $f\left( x \right) = ae^k$, where e is the irrational constant 2.71828182846...., or $f\left( x \right) = a\left( {{1 \over 2}} \right)^{{x \over h}}$ $f\left( x \right) = a\left( 2 \right)^{{x \over d}}$, where h is the half-life (for decay), or d is the doubling time (for growth).
