From your graph, I suggest the following:

 

1. (-inf, -4) U (-2, 3) U (4, 13)

 

2. (-4, -2) U (3, 4) U (13, inf)

 

3. (-3, -1) U (0, 2)

 

4. (-5, -3) U (-1, 0) U (2, 4) U (4, inf)

 

5. (-5, -1) U (-1, 1)

 

6. (1, 3)

 

7. (-inf, -5) U (3, 4) U (4, inf)

 

8. (-inf, -5)

Extrapolate the right-most line. For every 2 units reduction in y it increases by 3 units in x.
