OpenStudy (matt101):

If it is just these four points and you are not expected to find an equation that all four satisfy, the domain would be {-1,1,3,5} and the range would be {-5,-1,3,7}.

is the relation in the question above a function?

OpenStudy (matt101):

Yes. There is only one y-value for each x-value.
