Domain and Range of the Logarithmic Function
Let f(x) = logBx.
Since the exponential function is the inverse of the logarithmic function, the range of the logarithmic function is the domain of the exponential function which is the set of all real numbers.
The domain of the logarithmic function is the range of the exponential function which is given by the interval (0 , + infinity).
