Question

Find the domain and range of the relation

{(22,21), (5,-16), (20, -24), (-17,4), (-9,2)}

Answer 1

The domain would be all of the X values in order from least to greatest. So…
D: {-17,-9,5,20,22}

The range would be all of the Y values in order from least to greatest. So…
R: {-24,-16,2,4,21}

For future reference: if there was a repeated number in either the domain or range, you wouldn’t put it down multiple times, just once.
