(3,-6) because you can't have two of the same x's in a function

ANSWER: Either
(3,8) or
(3,-6)


Step-by-step explanation

For a relation to be a function, it must either be a one-to-one relation or many-to-one-relation.


The above relation is one-to-many relation because 3 is mapping on to -6 and 8.


To make the above relation a function, we must remove one of the points containing 3 as first coordinate.



This will make the relation one-to-one which then becomes a function.


See attachment for diagrammatic representation.
