An inverse function is always represented like this: $f:f(x) \rightarrow f ^{-1}:f ^{-1}(x) <=>f ^{-1}=\frac{ 1 }{ f(x) }$ So, for the function: $f(x)=\frac{ 3x +2 }{ 4 }$ it's inverse will be: $f ^{-1}(x)=\frac{ 1 }{ \frac{ 3x +2 }{ 4 } }$

THEN do the reverse

inverse

6. Owlcoffee

Okay, why?

7. Owlcoffee

use the definition of inverse function: $f(a)=b$ $f ^{-1}(b)=a$
