You can put this solution on YOUR website!
Determine whether each relation is a function.
{5,3), (1,4), (-6,5),(1,6),(-2,7)
Ans: The x = 1 value is repeated with different y-values,
so this is not a function.
---------------------------
and
{(2,3),(-3,-4),(-1,3),(6,7)
Ans: The x values are not repeated so this is
a function.
