If f(x)=1/2x+14, then f^-1(x)=

Answer 1

f(x) is same as y so first replace f(x) with y
\[\large\rm \color{ReD}{y}=\frac{ 1 }{ 2\color{blue}{x} }+14\]then switch x and y
\[\large\rm \color{blue}{x}=\frac{ 1 }{ 2\color{reD}{y}}+14\]
now that equation for y

Answer 2

btw it's \[\frac{ 1 }{ 2x }+14 ~~~~~or~~~~~~~~~~\frac{ 1 }{ 2x+14 }\]

Answer 3
