Multiple Choice

A one-to-one function f is given. $\text { Find } \mathrm { f } ^ { - 1 } ( \mathrm { x } )$ and graph fwith a solid line and $f ^ { - 1 } ( x )$ with a dotted line on the same axes.
- $f ( x ) = 4 x$

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

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

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

D) $\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \frac { \mathrm { x } } { 4 }$
