3. The derivative of a function f is given by f'(x) = (-2x -2) e*, and f(0) = 3. A. The function f has a critical point at x = -1. At this point, does f have a relative minimum, a relative maximum, or neither? Justify your answer. (2 points) B. On what intervals, if any, is the graph of f both increasing and concave down? Explain your reasoning. (4 points) C. Find the value of f(-1). (3 points)
