blurbendy · Answer

your domain is all the x in the ordered pairs

(x, y)

there are NO duplicates in sets though

hero · Answer

The domain of a relation is the set of x coordinates of each (x,y) pair.

hero · Answer

For example, if you had the relation (2, 3), (4, 5), (6, 7), (8, 9), then the domain of this relation would be x = {2, 4, 6, 8}

hero · Answer

The domain does not have to be listed in the order given. {2, 4, 6, 8} means the same as {4, 2, 8, 6} which means the same as {8, 4, 6, 2} and et cetera.
