Question

Choose the relation with a domain of {−2, −1, 2, 4, 5}.

R = {(−3, 5), (−6, 4), (−2, 2), (5, −2) (0, −1)}

R = {(−2, 1), (2, 2), (4, 5)}

R = {(5, −3), (4, −6), (2, −2), (−2, 5) (−1,0)}

R = {(5, 4), (2, 2), (1, −2)}

Answer 1

domain is your x values

Answer 2

(x,y) hint

Answer 3

so would it be the third choice?

Answer 4

Each ordered pair contains an x and a y value... (x,y)
In the third selection the x values are 5,4,2,-2,-1.
The question had these same values in a different order.
Yes, it is the third choice.

Answer 5

ok thanks to both of u!
