Question 5 > - The function f(1) = – 2.13 – 7.53x2 + 55.692x – 0.46 is increasing on the open interval ( A It is decreasing on the open interval ( -00, ) and the open interval ( , O). The function has a local maximum at Submit Question

Question 6 3.1 +7 Consider the function f(1) = For this function there are two important intervals: (- 00, A) 30 + 3 and (A, ..) where the function is not defined at A. Find A For each of the following intervals, tell whether f(2) is increasing (type in INC) or decreasing (type in DEC). (-0, A): (A,00) Note that this function has no inflection points, but we can still consider its concavity. For each of the following intervals, tell whether f(x) is concave up (type in CU) or concave down (type in CD). (- 00, A): (A,00) Submit Question
