Multiple Choice

Find the inverse of the one-to-one function.
- $$f ( x ) = \frac { 4 x + 7 } { 5 }$$

A) $f ^ { - 1 } ( x ) = \frac { 5 x - 7 } { 4 }$
B) $\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \frac { 5 \mathrm { x } + 7 } { 4 }$
C) $\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \frac { 5 } { 4 \mathrm { x } - 7 }$
D) $f ^ { - 1 } ( x ) = \frac { 5 } { 4 x + 7 }$
