Final answer:
The domain of the relation R{(3,-2), (1, 2), (-1,-4), (-1, 2)} is {-1, 1, 3}.
Step-by-step explanation:
The domain of the relation R{(3,-2), (1, 2), (-1,-4), (-1, 2)} is {-1, 1, 3}. The domain of a relation refers to the set of all input values (x-values) for which there is at least one corresponding output value (y-value). In this case, the x-values are -1, 1, and 3, because they appear as the first element of at least one ordered pair in the relation R.
