Multiple Choice

For the given functions f and g, find the requested function.
- $f ( x ) = \sqrt { 2 x } ; g ( x ) = - 3 x + 7 \quad$ Find $( f \cdot g ) ( x )$

A) $( f \cdot g ) ( x ) = - 6 x + 7 \sqrt { 2 x }$
B) $( f \cdot g ) ( x ) = - 3 x \sqrt { 2 x } + 7 \sqrt { 2 x }$
C) $( \mathrm { f } \cdot \mathrm { g } ) ( \mathrm { x } ) = - 6 \mathrm { x } ^ { 2 } + 14$
D) $( f \cdot g ) ( x ) = \sqrt { 2 x } + 21 x$
