b. Given $f(x) = 3^{x-2}$ algebraically determine the equation for $f^{-1}(x)$. (1 mark) $f(x) = 3^{x-2}$ $3^{x-2} = y$ $\ln(3^{x-2}) = \ln y$ $(x-2)\ln 3 = \ln y$ $x - 2 = \frac{\ln y}{\ln 3}$ $x = 2 + \frac{\ln y}{\ln 3}$ $f^{-1}(x) = \frac{\ln x}{\ln 3} + 2$ c. Describe the transformation using a mapping statement. (1 mark)
