Problem 6. The figure below shows a rough graph of / (z ), the derivative of lita (a twice-differentiable function). The values given in in parentheses refer to the objective areas between the curve and the r-axis. You are also told that f (4) - -4. 17+ (10) -2 6 (2) 24 -34 A. Compute f (-4). As usual, show all work. B. Your buddy Ron states that f (r ) has a local minimum at . - 1, State whether Ron is correct, or incorrect and explain your reasoning
