Determine the location and value of the absolute extreme values of f on the given interval, if they exist. 3 It f(x) = - 5csc x; 4 Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. (Type exact answers, using it as needed. Use a comma to separate answers as needed.) O A. The absolute maximum is at x = and the absolute minimum is at x = O B. The absolute maximum is |at x = , but there is no absolute minimum. O C. The absolute minimum is at x = , but there is no absolute maximum. OD. 3 TC There are no absolute extreme values for f(x) on 4 ' - 4 19 16 17
