Find the intervals on which f is increasing and the intervals on which it is decreasing. f(x) = - 2 cos (x)– v2x on [0,2x] Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. O A. The function is decreasing on the open interval(s) . The function is never increasing. (Simplify your answer. Use a comma to separate answers as needed. Type your answers in interval notation. Type an exact answer, using n as needed. Use integers or fractions for any numbers in the expression.) O B. The function is increasing on the open interval(s) The function is never decreasing. (Simplify your answers. Use a comma to separate answers as needed. Type your answers in interval notation. Type an exact answer, using a as needed. Use integers or fractions for any numbers in the expression.) O C. The function is increasing on the open interval(s) and decreasing on the open interval(s) (Simplify your answers. Use a comma to separate answers as needed. Type your answers in interval notation. Type an exact answer, using a as needed. Use integers or fractions for any numbers in the expression.) O D. The function is never increasing or decreasing.
