7. F is a function that is defined and continuous at all real numbers. The graph of F', the derivative of F, is shown below on the right. Use it to answer the questions below. (i) (4 points) In which interval(s) is the func- tion F increasing? Answer: 5 (ii) (6 points) Where is F concave down? Answer: (iii) (3 points) What are the critical values of F? -5 Answer: Graph of F'(x), the derivative of F(x) (iv) (9 points) Which, if any, of these critical values are relative minimum(s)? Which are relative maximum(s)? Which are neither
