The range of a relation is the set of values that the relation can take for each value of x.
If we observe the graph, we have the following points (from left to right):
(-5, 3), (-5, -4), (-4, 0), (-3, 5), (1, -1), (5, -2).
Then, we need to pick up the values for y (range of the relation):
{3, -4, 0, 5, -1, -2}
