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)}

aripotta · Answer

domain is all the x's in a set

aripotta · Answer

so which one do you think it is?

anonymous · Answer

the 2nd one? @AriPotta

aripotta · Answer

the second one has a domain of -2, 2, 4. so it's not the second one

anonymous · Answer

oh I see it's the third one because it includes all of them? @AriPotta

aripotta · Answer

yep :) good job
