please mark me guys

Answer 2

$\displaystyle\huge\red{\underline{\underline{Solution}}}$

TO DETERMINE

The inverse of the function f(x) = 4x

CALCULATION

$\sf{Here \: \: f(x) = 4x \: }$

$\sf{ {f}^{ - 1}(x) \: is \: the \: inverse \: of \: the \: function \: f(x) = 4x }$

$\sf{Let \: \: {f}^{ - 1} (x) = y}$

$\implies \sf{f(y) = x \: }$

$\implies \sf{4y= x \: }$

$\displaystyle \implies \sf{y = \frac{x}{4} \: }$

$\displaystyle \therefore \: \: \: \sf{ {f}^{ - 1}(x) = \frac{x}{4} \: }$

RESULT

$\boxed{ \displaystyle \: \: \: \sf{ {f}^{ - 1}(x) = \frac{x}{4} \: \: \: }}$
