Below, you are given a mapping diagram. create and justify a relation that represents a function with the given range. write your answers as ordered pairs. create and justify a relation that does not represent a function with the given range. write your answers as ordered pairs.

But we can assume there is a function f(x) such that: 

f(1) = 11

f(2) = 20

f(3) = 34

f(4) = 41

So the ordered pairs will be: (1, 11), (2, 20), (3, 34) and (4, 41) The justification is for each point in the domain: 1, 2, 3, 4 we have assumed a function that has one unique value in the range. So it is a function.
