Which relation is a function?
A. {(6, −4), (5, 8), (−3, 6), (−4, −4)}
B. {(7, 1), (4, 2), (−4, −4), (7, 3)}
C. {(6, 5), (−3, −2), (6, 4), (5, 8)}
D. {(5, 2), (−2, −8), (7, −1), (−2, 6)}

In mathematics, a function from a set of values for variable x to a set of values for variable y assigns to each element of x only one element of y. The set X is called the domain of the function and the set Y is called the codomain of the function.

On this note, since in Choice A, each x-value is mapped distinctively to one value of y, Choice A is a function.
