Determine the location and value of the absolute extreme values of fon the given interval, if they exist f(x) = 3 sin2x on [0,x] Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. (Type an exact answer, using it as needed. Use a comma to separate answers as needed.) O A. The absolute minimum is at x = but there is no absolute maximum O B. The absolute maximum is at x = but there is no absolute minimum O C. The absolute minimum is at x = and the absolute maximum is at X = O D. There are no absolute extreme values for f(x) on [0,x]
