Question

How do you find the range of the following relation R{(3,-5), (1,2), (-1, -4), (-1,2)}?

Answer 1

`R:{ -5, -4, 2}`

Explanation:

The range is the number on the right (the `y` coordinate)

`(3, color(red)(-5)), (1, color(red)(2)), (-1,color(red)( -4)), (-1,color(red)2)`

The range are `color(red)(-5), color(red)2, color(red)(-4), color(red)2`

If there's a repeated number write it once

Regarange the numbers from least to greatest

`R:{ -5, -4, 2}`
