Question

What is the range if f(x) =2x + 5 and domain: -1,0,3,7,10 ?

Answer 1

Range: `{ 3, 5, 11, 19, 25}`

Explanation:

Given`(fx)=2x+5`

If the Domain is restricted to
`color(white)("XXX"){-1, 0, 3, 7, 10}`
then the Range is
`color(white)("XXX"){f(-1), f(0), f(3), f(7), f(10)}`

`color(white)("XXX")= {3, 5, 11, 19, 25}`
