(c) Find all intervals where f is concave up. (d) Find all intervals where f is concave down. (e) Find all inection points of f ( x ). 5. (10 points) Suppose that f ( x ) is a twicedierentiable function and that the graph of y = f ( x ) is shown below. L M 3, M 1 R L 2, M 1 R y E f L x R (a) Which of the following best describes the value of f (0)? A. It is positive. B. It is negative. C. It is zero. D. Its sign cannot be determined from the graph. (b) Which of the following best describes the value of f 00 (3)? A. It is positive. B. It is negative. C. It is zero. D. Its sign cannot be determined from the graph.
