Final answer:
The domain of the relation is {1, -8, 9}, the range is {2, -8, 9}, and the relation is a function.
Step-by-step explanation:
The relation given is {(1,2), (-8,-8), (9,9)}. To find the domain of the relation, we need to determine the set of all possible x-values. In this case, the domain is {1, -8, 9}. To find the range, we need to determine the set of all possible y-values. In this case, the range is {2, -8, 9}.
Since each x-value in the relation corresponds to a unique y-value, the relation is a function.
Domain: {1, -8, 9}
Range: {2, -8, 9}
Function: Yes
