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

Explanation:

$Rearrange making x the subject$ $"Rearrange making x the subject"$

$\Rightarrow 4 x - 1 = y$ $rArr4x-1=y$

$\Rightarrow 4 x = y + 1$ $rArr4x=y+1$

$\Rightarrow x = \frac{1}{4} (y + 1)$ $rArrx=1/4(y+1)$

$convert y into x for inverse function$ $"convert y into x for inverse function"$

$\Rightarrow f^{- 1} (x) = \frac{1}{4} (x + 1)$ $rArrf^-1(x)=1/4(x+1)$
