That is a function, because
f(-2) = 0
f(2) = 1
f(4) = 2
f(6) = 3
f(8) = 4
That is, for two real numbers a and b, if f(a) = f(b) then a = b. As you can see, each element maps to one value.

Yes, as long as each value of x is paired with only one y.

Yes, because no first element of any pair is used twice.
