Question

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

1. {−1, 1, 3}

2. {−1, −1, 1, 3}

3. {−4, −2, 2, 2}

4. {−4, −2, 2}

Answer 1

{-1, 1, 3}

Answer 2

The range is the set of possible outputs. In this case, the outputs are -2, 2, and -4


So the range is choice 4. {-4, -2, 2}

Answer 3

hes right :) i did domain sorry...
