For the pair of functions, find the indicated sum, difference, product, or quotient.
-$$f ( x ) = 3 x - 9 , g ( x ) = 5 x - 2$$
Find $( f - g ) ( x )$.
A) $- 2 x - 7$
B) $2 x + 7$
C) $- 2 x - 11$
D) $8 x - 11$

To find $(f - g)(x)$, subtract $g(x)$ from $f(x)$: $f(x) - g(x) = (3x - 9) - (5x - 2) = 3x - 9 - 5x + 2 = -2x - 7$.
