D: {1, 2, -3, 0} R: {2, 4, -6, 0}

#### Explanation:

Think of it this way. Domain is your X-value, whereas the Range is your Y-value. And for your information, this relation is a function since the points have different X-values. If you had let's say {(1, 2), (1, 4), (-3, -6)}, then it would not be a function because you have two possible answers for x=1.
