The domain of the following relation: r: {(−4, 3), (3, 6), (−2, 1), (3, 6)} is

1, 3, 6}.

{–4, 3, −2, 3}.

{–4, −2, 3}.

no domain exists.

The domain of a function is the complete set of possible values of the independent variable. It is the set of all possible x-values that would describe the function. Therefore, the third option would be the correct answer. The set {–4,−2, 3} is the domain of the relation.
