Question

Does anyone know this??

The range of the following relation R {(3, −2), (1, 2), (−1, −4), (−1, 2)} is

A {−1, 1, 3}
B {−1, −1, 1, 3}
C {−4, −2, 2, 2}
D {−4, −2, 2}

Answer 1

The answer is D, because it is all of the y values. It only has 2 in there once because since it repeats, it doesn't need to be put in twice.
