And use 'U' for the union symbol. Problem 1 v Enter DNE if an answer does not exist. Problem 2 Problem 3 v f(x) = 5 sin(x) cos(x) on (-7, T) Problem 4 Problem 5 v a) Find the critical numbers of f. 4 4 4'4 (Separate multiple answers by commas.) Problem 6 v Problem 7 V b) Determine the intervals on which f is increasing and decreasing. Problem 8 ... f is increasing on: Problem 9 Problem 10 V f is decreasing on: c) Use the First Derivative Test to determine whether each critical point is a relative maximum, minimum, or neither. Relative maxima occur at a 371 5 4 '2 (Separate multiple answers by commas.) Relative minima occur at & = 4 (Separate multiple answers by commas.) Note: You can earn partial credit on this
