Question

Determine if the relation is a function.

{(0, 1), (2, 1), (3, 2), (4, 2)}
Answer

Function

Not a Function

Answer 1

Hint: A relation is not a function if you have one x value paired with more than one y value

ex:

{(1,3),(1,5),(2,7)} is NOT a function because x = 1 is paired with y = 3 and y = 5 at the same time

Answer 2

so is your relation a function? or no?
