Answer:
(x) = ![\frac{x}{4\\}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B4%5C%5C%7D)
Step-by-step explanation:
Let y = f(x) and rearrange making x the subject
y = 4x ( divide both sides by 4 )
x = ![\frac{y}{4}](https://tex.z-dn.net/?f=%5Cfrac%7By%7D%7B4%7D)
Change y back into terms of x
(x) = ![\frac{x}{4\\}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B4%5C%5C%7D)
