Find Domain Of Logarithmic Function Math

Therefore the the domain of the above logarithmic function is x a k or a k some more stuff on domain of logarithmic functions. Therefore the domain of the logarithmic function y log b x is the set of positive real numbers and the range is the set of real numbers. Remember that logarithmic functions and exponential functions are inverse functions so as expected the domain of an exponential is such that x r but the range will be greater than 0.
