20,000(x- 14) The rational function f(x) = 8x models the number of arrests, f(x), per 100,000 drivers, for driving under the influence of alcohol, as a function of a x2 -9 driver's age, x. Complete parts (a) through (c). a. Graph the function in a [0,70,5] by [0,400,20] viewing rectangle. Choose the correct graph below. OA. OB. Oc. OD. b. Describe the trend shown by the graph. O A. The graph shows a rapid increase as x approaches a maximum in the lower half of the domain, and a gradual decrease as x increases past the maximum. O B. The graph shows a rapid increase as x approaches a maximum in the upper half of the domain, and a gradual decrease as x increases past the maximum. O C. The graph shows a gradual increase as x approaches a maximum in the lower half of the domain, and a rapid decrease as x increases past the maximum. c. Use the ZOOM and TRACE features or the maximum function feature of your graphing utility to find the age that corresponds to the greatest number of arrests. How many arrests, per 100,000 drivers, are there for this age group? The age that corresponds to the greatest number of arrests is approximately years. (Round to the nearest tenth as needed.) The number of arrests. per 100.000 drivers, for this age group is approximately lick to select your answer(s).
