Find the Indicated Function and Write Its Domain in Interval $$n ( x ) = x - 5 , p ( x ) = x ^ { 2 } + 6 x , ( p \circ n ) ( x ) = \text { ? }$$

Multiple Choice

Find the indicated function and write its domain in interval notation.
- $$n ( x ) = x - 5 , p ( x ) = x ^ { 2 } + 6 x , ( p \circ n ) ( x ) = \text { ? }$$

A) $( p \circ n ) ( x ) = x ^ { 2 } - 4 x - 5$ ; domain $( - \infty , - 6 ) \cup ( - 6 , \infty )$
B) $( p \circ n ) ( x ) = x ^ { 2 } + 6 x - 5$ ; domain $( - \infty , \infty )$
C) $( p \circ n ) ( x ) = x ^ { 2 } + 6 x - 5 ;$ domain $[ 0 , \infty )$
D) $( p \circ n ) ( x ) = x ^ { 2 } - 4 x - 5$ ; domain $( - \infty , \infty )$
