Final answer:
The domain is {-2, -1, 0, 1, 2} and the range is {7, 5, 3, 1}.
Step-by-step explanation:
The domain of a relation or function is the set of all input values or x-values. In this case, the x-values are -2, -1, 0, 1, and 2, so the domain is {-2, -1, 0, 1, 2}.
The range of a relation or function is the set of all output values or y-values. In this case, the y-values are 7, 5, 3, and 1, so the range is {7, 5, 3, 1}.
