If the Function Is One-To-One, Find Its Inverse $f ( x ) = - 8 x + 1$

question 68

Multiple Choice

If the function is one-to-one, find its inverse. If not, write "not one-to-one."
- $f ( x ) = - 8 x + 1$

• A) \(f ^ { - 1 } ( x ) = - \frac { 1 } { 8 } x - 1\)
• B) \(\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = - \frac { 1 } { 8 } \mathrm { x } - \frac { 1 } { 8 }\)
• C) \(\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = - \frac { 1 } { 8 } \mathrm { x } + \frac { 1 } { 8 }\)
• D) \(f ^ { - 1 } ( x ) = - \frac { 1 } { 8 } x + 1\)
