Question

The domain and range of the following relation: R: {(5, -3), (1, 9), (-5, -4), (-8, 9)} is

Domain: {-4, -3, 9}, Range: {-8, -5, 1, 5}

Domain: {-8, -5, 1, 5}, Range: {-4, -3, 9}

Domain: {(5, -3), (1, 9), (-5, -4), (-8, 9)}, Range: Does not exist

Domain: Does not exist, Range: {(5, -3), (1, 9), (-5, -4), (-8, 9)}
