For the given rational functions f(x) and g(x), f(x) -g(x).
-$$f ( x ) = \frac { 15 } { x - 3 } , g ( x ) = \frac { 5 x } { x - 3 }$$
A) $- \frac { 5 } { x - 3 }$
B) $- 5$
C) $\frac { 5 } { x - 3 }$
D) 5

The functions have the same denominator, so subtract the numerators: $15 - 5x = -(5x - 15) = -5(x - 3)$. Simplifying gives $-5$.
