Final answer:
The domain of the linear relation {(0,-6), (1,-4), (2,-2), (3,0)} is {0, 1, 2, 3}.
Step-by-step explanation:
The domain of a linear relation refers to the set of all possible x-values that the relation can take on. In this case, the given linear relation {(0,-6), (1,-4), (2,-2), (3,0)} has x-values of 0, 1, 2, and 3.
Therefore, the domain of the linear relation is {0, 1, 2, 3}.
