Question

What is the range of R: {(3, −2), (1, 2), (−1, −4), (−1, 2)}?

Answer 1

Range of `R: {-2, 2, -4}`

Explanation:

Given: `R = {(3, −2), (1, 2), (−1, −4), (−1, 2)}`

The Domain is the valid input (usually `x`).

The Range is the valid output (usually `y`).

The set `R` is a set of points `(x, y)`.

The `y`-values are `{-2, 2, -4}`
