Question 203

Multiple Choice

Find the inverse of the one-to-one function.
- f(x) =53x+7f ( x ) = \frac { 5 } { 3 x + 7 }


A) f1(x) =53x73\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \frac { 5 } { 3 \mathrm { x } } - \frac { 7 } { 3 }
B) f1(x) =53y73\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \frac { 5 } { 3 \mathrm { y } } - \frac { 7 } { 3 }
C) f1(x) =3x+75\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \frac { 3 x + 7 } { 5 }
D) f1(x) =7353x\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \frac { 7 } { 3 } - \frac { 5 } { 3 \mathrm { x } }
