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 what x and y
do you know :)

Answer 2

domain is x values
and in order pair x values is always is first one
now look your relation
the domain they gave you if all of that is first in order pair then that is your answer
and don't worried about order 4 can be come first then 2
