Final answer:
The domain of a relation is the set of all possible x-values, and the range is the set of all possible y-values.
Step-by-step explanation:
A relation represents a set of ordered pairs where each input (x-value) is paired with one or more outputs (y-values). The domain of a relation is the set of all possible x-values, and the range is the set of all possible y-values.
In the given relation, the domain consists of the values -9, -8, and 9. The range consists of the values -9, -3, and not a function.
