Question

Which represents the inverse of the function
f(x) = 4x?

Answer 1

4th option

Explanation:

let y = f(x) , then rearrange making x the subject, that is

y = 4x ( divide both sides by 4 )

`(1)/(4)` y = x

Change y back into terms of x with x =
`f^(-1)` (x) , then

`f^(-1)` (x) = h(x) =
`(1)/(4)` x
