The logarithmic function with base a, f(x) = logax , is the inverse of the exponential function with base a, g(x) = ax .

Reminder. The graph of an inverse function can be obtained by reflecting the graph of the original function in the line y = x .

Graph of f(x) = log a x and g(x) = ax , 0 < a < 1 | Graph of f(x) = log a x and g(x) = ax , a > 1
