Since domain is all allowed x values, the domain of this set of (x;y) ordered pairs is {4,5,6}
Since range is all the allowed y values, the range is {4,5,6}.

Explanation:

Since domain is all allowed x values, the domain of this set of (x;y) ordered pairs is {4,5,6}

Since range is all the allowed y values, the range is {4,5,6}.
