Given functions f and g, perform the indicated operations.
-$$f ( x ) = 4 x + 5 , \quad g ( x ) = 3 x + 3$$
A) $( - \infty , \infty )$
B) $( - \infty , 0 )$ or $( 0 , \infty )$
C) $( 0 , \infty )$
D) $( - \infty , - 4 )$ or $( - 4 , \infty )$

The domain of both $f(x) = 4x + 5$ and $g(x) = 3x + 3$ is all real numbers, $( - \infty , \infty )$, since there are no restrictions on $x$ for either function.

Given Functions F and G, Perform the Indicated Operations f(x)=4x+5,g(x)=3x+3f ( x ) = 4 x + 5 , \quad g ( x ) = 3 x + 3f(x)=4x+5,g(x)=3x+3
