The domain of the following relation R {(6, −2), (1, 2), (−3, −4), (−3, 2)} is (1 point) a
{−3, −3, 1, 6}

b
{−4, −2, 2, 2}

c
{−4, −2, 2}

d
{−3, 1, 6}

I believe the answer is D because domain is X and it is always (X,Y) so you take the X’s of the points and put them in order least to greatest and that will be your domain for this problem hope this helps
