question 110

Multiple Choice

Find the inverse function f-1 of the function f.
- $$f ( x ) = 7 \cos x + 4$$

• A) \(\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = 7 \cos ^ { - 1 } x + 4\)
• B) \(f ^ { - 1 } ( x ) = \cos ^ { - 1 } \left( \frac { x + 4 } { 7 } \right)\)
• C) \(\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \sin \left( \frac { \mathrm { x } - 4 } { 7 } \right)\)
• D) \(f ^ { - 1 } ( x ) = \cos ^ { - 1 } \left( \frac { x - 4 } { 7 } \right)\)
