Answer:  A. (-∞, -2) ∪ (-1, 0)

              B. (2, -1) ∪ (0, ∞)

               C. None

Step-by-step explanation:

Let's look at the graph from left to right to see what direction it is going:

  • It is increasing (↑) from x = -∞ to x = -2    
  • It is (↓) decreasing from x = -2 to x = -1
  • It is increasing (↑) from x = -1 to x = 0
  • It is (↓) decreasing from x = 0 to x = ∞

There are no straight lines so there are no intervals when it is constant.
