Question

What is the range if f(x) =1/2x - 2 and domain: -1/2,0,3,5,9 ?

Answer 1

The Range of `f(x)` with the given Domain is `{-2.25, -2, -0.5, 0.5, 2.5}`

Explanation:

Given the Domain `{-1/2, 0, 3, 5, 9}` for a function `f(x) = 1/2x-2`

the Range of `f(x)` (by definition) is

`{f(-1/2), f(0), f(3), f(5), f(9)}`

`={-2.25, -2, -0.5, 0.5, 2.5}`
