Question 245882
Hi i really need help with this question: Alex states that the relation below is not a function. Lillian says that it is a function. Who is correct? Explain your reasoning. 
Relation { (13,14), (12,5) , (16,7), (13, 14), (-2, 33), (13, 14}
-------------
It is a function because each DIFFERENT x value has only one y value.
