A compact way of rephrasing the point that the base-ਫਰਮਾ:Math/sandbox logarithm of ਫਰਮਾ:Math/sandbox is the solution ਫਰਮਾ:Math/sandbox to the equation ਫਰਮਾ:Math/sandbox is to say that the logarithm function is the inverse function of the exponential function. Inverse functions are closely related to the original functions: the graphs of the two correspond to each other upon reflecting them at the diagonal line ਫਰਮਾ:Math/sandbox, as shown at the right: a point ਫਰਮਾ:Math/sandbox on the graph of the exponential function yields a point ਫਰਮਾ:Math/sandbox on the graph of the logarithm and vice versa. Moreover, analytic properties of the function pass to its inverse function. Thus, as the exponential function ਫਰਮਾ:Math/sandbox is continuous and differentiable, so is its inverse function, ਫਰਮਾ:Math/sandbox. Roughly speaking, a differentiable function is one whose graph has no sharp "corners".
