Question

If G = {(-1, 7),(-8, 2),(0, 0),(6, 6)), then the range of G is

{(7,-1), (2,-8),(0, 0),(6, 6)}
(-8,-1 ,0, 6)
(0,2, 6, 7)

Answer 1

`\{0, 2, 6, 7\}`

Explanation:

You are given the relation
`G = \{(-1, 7),(-8, 2),(0, 0),(6, 6)\}`

This means that

`f(-1)=7\\ f(-8)=0\\f(0)=0\\f(6)=6`

The input values of this relation are
`-1,\ -8,\ 0,\ 6`, so the domain of this relation is
`\{-8,-1,0,6\}`

The output values of this relation are
`7,\ 2,\ 0,\ 6`, so the range of this relation is
`\{0, 2, 6, 7\}`
