Step-by-step explanation:
Observing the picture
1) For y=-1
The answer is undefined (there is no corresponding value for x)
2) For y=0
we have the points (-3,0) and (6,0)
therefore
x=-3, x=6
3) For y=2
we have the points
(-2.25,2)
(0.75,2)
(4,2)
therefore
x=-2.25, x=0.75, x=4
3) For y=3
we have the points belong to the interval [-2,0]
so
