    ok :) soo, a group of coordinates is a function when there are no coordinates that have the same x-value but different y-value.

    yes it is a function because all elements in domain have a corresponding element in range and no domain has corresponding multiple values in range

    so (1, 4) and (1, 5) is not because x is same, but y is different
