Perform the Requested Operation or Operations $f ( x ) = \sqrt { x + 8 }$

Perform the requested operation or operations. Find the domain of each.
- $f ( x ) = \sqrt { x + 8 }$ and $g ( x ) = | x - 6 |$
Find $f g$ .

A) $| x - 6 | \sqrt { x + 8 } ;$ domain: $( 6 , \infty )$
B) $\sqrt { x ^ { 2 } + 2 x - 48 }$ ; domain: $( - \infty , - 8 ) \cup ( 6 , \infty )$
C) $\left| x ^ { 2 } + 2 x - 48 \right|$ ; domain: $( - \infty , \infty )$
D) $| x - 6 | \sqrt { x + 8 }$ ; domain: $( - 8 , \infty )$
