Question

What are the domain and the range of the relation?

{(−3, 1), (−6, 7), (0, 9), (2, −1), (8, 8), (11, 5)}

Choose exactly two answers that are correct.

A.
domain: {−6, −3, 0, 2, 8, 11}

B.
domain: {–1, 1, 5, 7, 8, 9}

C.
range: {–1, 1, 5, 7, 8, 9}

D.
range: {−6, −3, 0, 2, 8, 11}
Medal to who answers correctly!

Answer 1

domain is all input values that are contained within the set
range would be values that would be output using the input

your set has coordinates, so your x value is your input, so all x values are domain
your y values are output so they are your range

Answer 2

ok thank you!, can you possibly walk me through the problem now?

Answer 3

well a coordinate is usually
(x,y)

so if I had a set
{(1,2), (3,4)}

my x coordinates, 1 and 3 are my domain so the domain is
domain {1,3}

my range are the y coordinates 2 and 4
range {2,4}

Answer 4

ohh lol ok thank you simple as that
