Question 135

Multiple Choice

Find f - -1 ( x ) . f(x) =78x−67f ( x ) = \frac { 7 } { 8 } x - \frac { 6 } { 7 }


A) f−1(x) =x+67f ^ { - 1 } ( x ) = x + \frac { 6 } { 7 }
B) f−1(x) =87x+4849f ^ { - 1 } ( x ) = \frac { 8 } { 7 } x + \frac { 48 } { 49 }
C) f−1(x) =87x−4849f ^ { - 1 } ( x ) = \frac { 8 } { 7 } x - \frac { 48 } { 49 }
