Hint:  If by adding an extra pair to the relation you have a duplicate value of x (thats the first number in the pair) then its not a function.

welshfella · Answer

So which one of the choices gives you a duplicate x-value?

b?

welshfella · Answer

No  - there is no  x value 0 in the original relation.

No  check the x values in the choices against the x-values in the question
