Find f - -1 ( x ). f ( x ) = $-$ 9 x $-$ 4
A) $f ^ { - 1 } ( x ) = \frac { x + 4 } { 9 }$
B) $f ^ { - 1 } ( x ) = - \frac { x + 4 } { 9 }$
C) $f ^ { - 1 } ( x ) = - \frac { x } { 9 } + \frac { 4 } { 9 }$

To find the inverse function, we first replace f(x) with y:
y = -9x - 4
Next, we swap the positions of x and y and solve for y:
x = -9y - 4
x + 4 = -9y
- (x + 4)/9 = y
Therefore, the inverse function of f(x) is f^-1(x) = -(x+4)/9.
