As is the case with all inverse functions, we simply interchange \(x\) and \(y\) and solve for \(y\) to find the inverse function. To represent \(y\) as a function of \(x\), we use a logarithmic function of the form \( y = \log_b(x) \). The base \(b\) logarithm of a number is the exponent by which we must raise \(b\) to get that number.
