Is the set of positive real numbers and the range is the set of real numbers. Therefore, the domain of the logarithmic function Note that the logarithmic functionisįor negative numbers or for zero. Remember that since the logarithmic function is the inverse of the exponential function, the domain of logarithmic function is the range of exponential function, and vice versa. Has the domain of set of positive real numbers and the range of set of real numbers. The inverse of an exponential function is a logarithmic function. Therefore, the range of the function is set of real positive numbers or , the value of the function tends to zero and the graph approaches So, the domain of the function is set of real numbers. The function is defined for all real numbers. Graph the function on a coordinate plane. Then the domain of the function remains unchanged and the range becomesįind the domain and range of the function We still have the whole real line as our domain, but the range is now the negative numbers, If we put a negative sign in frontto get the equation axis, but the domain and range do not change: values for which the function is defined, while the Domain and Range of Exponential and Logarithmic Functions
