For the pair of functions, perform the indicated operation.
-$f ( x ) = 3 x + 8 , g ( x ) = 4 x + 6 \quad$ Find $( f \cdot g ) ( x )$
A) $12 x ^ { 2 } + 50 x + 48$
B) $7 x ^ { 2 } + 50 x + 14$
C) $12 x ^ { 2 } + 48$
D) $12 x ^ { 2 } + 38 x + 48$

To find $(f \cdot g)(x)$, you multiply $f(x)$ by $g(x)$: $(3x + 8)(4x + 6) = 12x^2 + 24x + 32x + 48 = 12x^2 + 56x + 48$.

For the Pair of Functions, Perform the Indicated Operation f(x)=3x+8,g(x)=4x+6f ( x ) = 3 x + 8 , g ( x ) = 4 x + 6 \quadf(x)=3x+8,g(x)=4x+6
