# Exponential function, real

The function \$y=e^x\$, also denoted by \$y=\exp x\$. Sometimes the function \$y=a^x\$ for any base \$a>0\$ is also called an exponential function.

See also Exponential function; Exponent; \$e\$ (number). The inverse of the exponential function is the logarithmic function (cf. also Logarithm of a number). The value of the exponential function at a point is also called the antilogarithm of this point.
