If 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.
