(e) What is the acceleration when t = 5 hours? (7) (10 points) Sketch the graph of a function satisfying: f (2) = 4, f (4) = 0, f (2) = 0, f (4) = 0, f 00 ( x ) < 0 for x < 1, and f 00 ( x ) > 0 for x > 1. (8) (25 points) For the funtion f ( x ) = 11 + 9 x3 x 3x 3 . (a) Give f ( x ). (b) Give f 00 ( x ). (c) Find all extrema. Use f 00 ( x ) to say whether each is a relative maximum or minimum. (d) Find all inection points. (e) Sketch the graph. 1...
