**Damon**, Monday, June 9, 2008 at 3:26pmIf it only has one value of y for each value of x, it is a function.

That is the case here.

x has values -2 -1 0 1 3

y has values 1 -2 -3 6

So a is correct.

It does not matter that y is -2 twice, because it is at different x values.

if y were -2 and +2 at the same x, then it would be a problem and it would not be a function.
