(2) 2. Examine the graph of the function below. What are the x-values of the critical numbers? Critical Numbers:8. Shown below is the graph of f'(x). Use it to answer the following questions about f (x) a) On what interval(s) is f(x) increasing? 20 b) On what interval(s) is f(x) decreasing? X 1-6 4 -2 10 c) On what open intervals is f(x) concave down? d) On what open intervals is f(x) concave up? e) State the x-value(s) at which f(x) has a point of inflection. f) State the critical number(s)11. What can you conclude about the point (4, f(4)) if: Information What happens here f'(4) =0 and f"(4) =-6 f'(4) =0 and f"(4) =3 f'(4) =0 and f"(4) =0
