For the given functions f(x) and g(x), find (f ∙ g)(x) or $ \left(\frac{f}{g}\right)(x) $ as indicated.
-$$f ( x ) = - 10 x , g ( x ) = - 7 x + 5$$
Find $( f \cdot g ) ( x )$.
A) $20 x ^ { 2 }$
B) $70 x ^ { 2 } + 5$
C) $70 x ^ { 2 } - 50 x$
D) $- 7 x ^ { 2 } - 50 x$

\begin{align*}
(f\cdot g)(x) &= f(x)\cdot g(x) \
&= (-10x)\cdot(-7x+5) \
&= 70x^2 - 50x \
\end{align*}
