The graph of an exponential function, f, is given below. We will soon discuss this graph in great detail. The inverse function of an exponential is a logarithmic function (again, more on both functions soon). Using the two given reference points, sketch the graph of the given function f and its inverse, along with the identity function y = . 10 9 8765-13 2 -1, 2 7 8 9 10 Use the middle graphing tool to graph f (the given function) and use the right-most graphing tool to graph f . Use the left-most graphing tool to graph the identity function. Notice how the graphs are symmetric about the line y = c. 10 10 -9 -8 -7 -6 -5 -4 -3 -2 - 1 2 3 4 5 6 7 8 9 10
