Question

State the domain of the relation {(0,5), (5,2), (0, -4), (1,5)}.

O A. D = {0,5}
O B. D = {0, 1, 5}
C.
D = {4, 2,5}
O D.
D = {-4,0, 1, 2, 5)

Answer 1

B.

Explanation:

The domain of a relation is all the x-coordinates in the relation, where no x-coordinate repeats. In the relation {(0,5), (5,2), (0,-4), (1,5)}, the domain is {0, 1, 5} because those are the only x-coordinates in the points.

Therefore, the answer is B.
