5. A function f is continuous and twice differentiable for all values of x. The figure above shows the graph of f?, the derivative of function f on the closed interval [?4,2]. The graph of f? has horizontal tangents at x=?1 and x=1.5. The areas of regions A,B, and C are 20,10 , and 6 , respectively, and f(2)=3. (A) Find all x-values on (?4,2) such that the function f has a local minimum. Justify your answer. (B) Find all x-values on (?4,2) such that the graph of f has a point of inflection. Justify your answer. (C) Evaluate limx?1?x+12f(x)?. Explain your reasoning. (D) Evaluate limx??2?x+2f(x)+1?. Explain your reasoning.
