It would be (1, 8)
Only look at the x-values first. If they are all different, it is a function. If one wants to make it NOT a function, pick an x-value in this instance of 1,4, or 7. (1, 2) is the same, so that doesn't affect the function, but picking (1, 8) has two different values for f(x) and is NOT now a function.
(-2, 3).
The others have the same x value as one of the values in the function.
