Question
Which of the following is a relation but not a function? {(-10,1),
(1,8), (-4, -2)} ....{(-4,1), (1,1), (-2, -2)} ...{(-5,1), (1,-7), (21,
-2)} ...or none of these?  

Answer
{(-10,1),(1,8),(-4,-2)}
{(-4,1),(1,1),(-2,-2)}
{(-5,1),(1,-7),(21,-2)}

For a function not to be a function, the x-values cannot be the same.

So so far as i can tell, there is no x-value that repeats, so all of these are relations and functions, so i cannot find a relation that isn't a function.
