Answer:
Step-by-step explanation:
Here you have a relation with just five points.
Each point has an input value and an output value.
The domain is the set of all input values. Here, that is {3, 6, 0}. Notice that 3 and 6 each show up more than once as inputs. In other words, when the input is either 3 or 6, two output values are defined. This is a sure giveaway that this relation is not a function. The unique output values are {-2, 6, 1, 2}. This set is the range of the given relation.
