For the exponential function answer the following. f(x) = 7(0.4*) (a) Calculate the percentage change and average rate of change of f for each of the following intervals. (Round your answer to three decimal places.) i. From x = 1 to x = 3 average rate of change % percent change ii. From x = 3 to x = 5 average rate of change percent change i. From x = 5 to x = 7 average rate of change percent change (b) On the basis of the results in part (a) and the characteristics of exponential functions presented in Chapter 1, what generalizations can be made about percentage change and average rate of change for an exponential function? For an exponential function, the average rate of change between two points -Select- change -Select- but the percent
