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