Question

Which represents the

inverse of the function f(x) = 4x?
O h(x) = x + 4
• h(x) =x-4
H(x) = 3/4x
h(x) = 1/4x

Answer 1

4th option

Explanation:

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

y = 4x ( divide both sides by 4 )

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

change y back into terms of x with x = h(x) , then

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