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

Anton [14]

Answer:

$f^{-1}$ (x) = $\frac{x}{4\\}$

Step-by-step explanation:

Let y = f(x) and rearrange making x the subject

y = 4x ( divide both sides by 4 )

x = $\frac{y}{4}$

Change y back into terms of x

$f^{-1}$ (x) = $\frac{x}{4\\}$
