In the first table you can observe that the input value 2 has two different output values:
Therefore, this relation is not a function.
Notice that in the second table the input value -4 has two different output values:
Therefore, this relation is not a function.
In the set , observe that the input value -5 has two different output values:
Therefore, this relation is not a function.
