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

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) $f ^ { - 1 } ( x ) = 9 ( x - 4 )$
