Final answer:
The domain of the relation is (-3, -1, 0, 1, 5).
Step-by-step explanation:
The domain of a relation is the set of all x-values in the relation's ordered pairs. In this case, the relation is given by (-3,-4), (-1,2), (0,0), (1,3), (5,4). To find the domain, we need to list all the x-values in these ordered pairs, which are -3, -1, 0, 1, and 5. Therefore, the domain of the relation is (-3, -1, 0, 1, 5), which can be found in option A.
