Answer:
D. (3, 4), (-2, 2), (6, 1), (-8, 2).
Step-by-step explanation:
A relation is a set of one or more ordered pairs. A function is a relation in which each element of the domain is paired with exactly one element of the range. In other words, a function does not have two or more y-coordinates for any x-coordinate. The only answer choice meeting this requirement is (3, 4), (-2, 2), (6, 1), (-8, 2).
