Answer 2

For this case we must indicate if the given table represents a function.

By definition, a function is a relation between two sets in which each element of the first set is related to a single element of the second set.

It is observed in the table, that each value of the starting set has associated a single element in the arrival set.

Therefore, we have that it is a function because each value of "x" corresponds to a value of "y".
