Question

I am giving a brainliest to the best answer

Answer 1

Answer:

A

Step-by-step explanation:

Given

f(x) = $\frac{x+3}{4}$

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

y = $\frac{x+3}{4}$ ( multiply both sides by 4 )

4y = x + 3 ( subtract 3 from both sides )

4y - 3 = x

Change y back into terms of x

$f^{-1}$(x) = 4x - 3 → A
