Find the Inverse of the Given Function and Express It $y = f ^ { - 1 } ( x )$

question 1

Multiple Choice

Find the inverse of the given function and express it in the form $y = f ^ { - 1 } ( x )$ . Verify the result by showing that $\left( f \circ f ^ { - 1 } \right) ( x ) = \left( f ^ { - 1 } \circ f \right) ( x ) = I ( x )$ . $x + 4 = 9 y$

• A) \(f ^ { - 1 } ( x ) = 4 x + 9\)
• B) \(f ^ { - 1 } ( x ) = 9 x - 4\)
• C) \[f ^ { - 1 } ( x ) = 4 x - 9\]
• D) \(f ^ { - 1 } ( x ) = 9 x + 4\)
• E) \(f ^ { - 1 } ( x ) = 9 ( x - 4 )\)
