Homework: 3.5 Homework Question 9, 3.5.21-PS HW Score: 62.31%, 8.1 of 13 points Save Part 1 of 6 O Points: 0 of 1 The pressure of the oil in a reservoir tends to drop with time. By taking sample pressure readings for a particular oil reservoir, petroleum engineers have found that the change in pressure is given by the function P(t) = to - 8t" + 16t, where t is time in years from the date of the first reading. (a) Find the following: P(0), P(2), P(3), P(5) (b) Graph P(t) (c) Over what period is the change (drop) in pressure increasing? decreasing? (a) Evaluate P(0), P(2), P(3), and P(5) P(0) =
