DETAILS Profit. Suppose the profit of a product is modelled by the function f(x) = 2x" - 30x* + 96x + 9 The absolute maximum value of f(x) on [1, 7] is Of = -119 Of = 97 Of = 1 Of = 9 Of = 12 Of = -103 There is no maximum Of = 7 Submit Answer View PrevioObject Height. Suppose an object is thrown straight up from the ground . The height after f seconds is given by the formula h(t) = -203 + 84t? + 151 (a) The time in seconds, rounded to 4 decimal places, when the object reached the highest point was O 63 s O 151 5 O 21 s 28 s )None of the other answers Oos (b) The height is maximized at the critical point x = a because the second derivative test found Of (a) = 0 O (a) was negative to the left of x = a and positive to the right () (a) was positive to the left of x = a and negative to the right Submit
