question 28

Multiple Choice

Find the inverse function f-1 of the function f.
- $$f ( x ) = \cos ( x - 9 ) - 5$$

• A) \(\mathrm { f } ^ { - 1 } ( \mathrm { x } ) = \cos ^ { - 1 } ( \mathrm { x } - 5 ) - 9\)
• B) \(f ^ { - 1 } ( x ) = \cos ^ { - 1 } ( x + 5 ) + 9\)
• C) \(f ^ { - 1 } ( x ) = \cos ^ { - 1 } ( x + 9 ) + 5\)
• D) \(f ^ { - 1 } ( x ) = \cos ^ { - 1 } ( x - 9 ) - 5\)
