1. On what intervals is f(x) concave up? (Use interval notation.)
Answer: (-4,–1)U(0,4)
2. On what intervals is f(x) concave down? (Use interval notation.)
Answer: (-infinity ,-4)U(-1,0)U(4, infinity)
3. Find the x-values of all inflection points of f(x). Separate your answers by a comma. If there are none, enter NONE.
Answer: -4,-1,0,4
4. On what intervals is f '(x) increasing? (Use interval notation.)
Answer: (-4,–1)U(0,4)
5. On what intervals is f '(x) decreasing? (Use interval notation.)
Answer: (-infinity,-4)U(-1,0)U(4, infinity)
6. Find the x-values of all local maxima of f '(x). Separate your answers by a comma. If there are none, enter NONE.
Answer: 4
