Question

Find the domain of {(1, -3), (2, 4), (3, 7), (3, 6)}

Answer 1

Answer:

{1,2,3}

Step-by-step explanation:

The domain is the set of x's for which the relation exists.

So the x in each pair is actually the first number per pair.

So the domain is {1,2,3} since the set of points is {(1, -3), (2, 4), (3, 7), (3, 6)}.
