Question

The range of the following relation R {(3, −5), (1, 2), (−1, −4), (−1, 2)} is

{−1, 1, 3}
{−5, −4, 2}
{−1, −1, 1, 3}
{−4, −5, 2, 2}

Answer 1

The range is all the y values...and just so u know, the domain is all the x values
so the range is : -5,-4,2

Answer 2

You can rewrite the relation R {(3, −5), (1, 2), (−1, −4), (−1, 2)} as the rule:

`3\rightarrow -5,\\1\rightarrow 2,\\-1\rightarrow -4,\\-1\rightarrow 2.`

The range of relation are all y that are maped to. In your case, the range of relation is the set

`\{-5,2,-4\}.`

Answer: correct choice is B.
