Multiple Choice

Evaluate the function for the given value of x.
- $$p ( x ) = x ^ { 2 } + 7 x , q ( x ) = \sqrt { x + 3 } , ( p \cdot q ) ( x ) = ?$$

A) $x + 3 + 7 \sqrt { x + 3 }$
B) $( p \cdot q ) ( x ) = \sqrt { \left( x ^ { 2 } + 7 x \right) ( x + 3 ) }$
C) $( p \cdot q ) ( x ) = \left( x ^ { 2 } + 7 x \right) \sqrt { x + 3 }$
D) $( p \cdot q ) ( x ) = x ^ { 2 } + 7 x \cdot \sqrt { x + 3 }$
