there's X and Y... right?
for a function: X is never repeated...

In a function the domain is never repeated. If you graph the ordered pairs then you can use the vertical line rule to tell if it is a function or a relation.

IF every element from first set has one and only one answer (arrow)in second set ,THEN IT IS A FUNCTION
If either any element from first set has more than one answer or has not THEN IT IS A RELATION AND NOT FUNCTION
