A is what I think

calculusxy · Answer

does the x and the y have any relation?
do they seem to be any functions (where you compute x with something to get y)?

anonymous · Answer

The answer is D. This is because there is no relation.

anonymous · Answer

thanks :)

anonymous · Answer

I believe the answer is C, but I'm not sure.

anonymous · Answer

Nevermind, it's D. The function is multiply by -1 then subtract 1

calculusxy · Answer

But any set of ordered pair is a relation, I believe.

anonymous · Answer

I'm not sure. I haven't learned this yet. I'm in 7th grade pre-algebra, so I only know the functions part of the question.

anonymous · Answer

@CiroR you are correct. The function is multiply by -1 then subtract 1. :)

calculusxy · Answer

all of these ordered pairs are a set. each has a function that is the same . don't they "relate" to one another?

anonymous · Answer

No because 4 doesn't come before 3. And it would have to be way different to make it a relation.

Does this help anyone?
