Easy -1.2 This is a straightforward recall question requiring knowledge that the inverse of y = e^x is y = ln(x), followed by sketching two standard graphs with basic intercepts. No problem-solving or novel insight required—purely routine knowledge and graph sketching skills.
Write down the inverse function of \(y = e^x\). On the same set of axes, sketch the graphs of \(y = e^x\) and its inverse function, clearly labelling the coordinates of the points where the graphs cross the \(x\) and \(y\) axes. [3]
