Determine whether each relationship is a function. state the domain and range of each relation.

By looking at the table we can determine that each element of the domain is paired with exactly one element of the range. Hence, it is a function.

D:

The domain of a function is the complete set of possible values of the independent variable in this case

-2 ≤ x ≤ 2R:

The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain in this case it will be

5 ≤ y ≤ 9
