For functions, x’s can’t repeat, so looking at the first problem, C is the only one where the first number in each coordinate (x,y) doesn’t repeat.


For the second, x = -2 means that no x is always -2 matter which y you would look at. So x’s repeat and it forms a vertical line. So it is not a function
