Suppose x 49 2'2 f(x) _ [0 9 + cos2 (t) dt. Find the critical number(s) of f(x). ANSWER: x = 7, 7 2 (Enter a number, a list of numbers separated by commas, or the word NONE.) Correct! Now, examine the behavior of the function f on intervals between the critical numbers by filling in the table below: _ _sign off': _v _v _v
