aripotta · Answer

do you know what domain means?

anonymous · Answer

@AriPotta yeah no potatos here lol,

aripotta · Answer

the domain is only a list of all the x's in a set

anonymous · Answer

@AriPotta so would it be D)

aripotta · Answer

no, because there's no point on that graph that has -1 as an x coordinate

aripotta · Answer

this is the set: {(–2, 1), (−2, -1), (1, 2), (1, 1), (1,-1)}

what are the x's that you see in there?

anonymous · Answer

there are none

aripotta · Answer

there are some lol. all coordinates are setup as (x,y) right? so the first number in each parentheses is an x
