Given the two functions $f$ and $g$, find $fg$ and identify the domain.
$f\(\left\)(x\(\right\))=\(\sqrt{x}\)$, $g\(\left\)(x\(\right\))=x+17$

• A. $\(\left\)(fg\(\right\))\(\left\)(x\(\right\))=\(\frac{\sqrt{x}\)}{17+x}$, Domain: $\(\left\)(-\(\infty\),0\(\right\]\rbrack\)$
• B. $\(\left\)(fg\(\right\))\(\left\)(x\(\right\))=17-\(\sqrt{x}\)$, Domain: $\(\left\)(0,\(\infty\]\right\))$
• C. $\(\left\)(fg\(\right\))\(\left\)(x\(\right\))=\(\sqrt{x}\)+17x$, Domain: $\(\left\[\lbrack\)0,\(\infty\]\right\))$
• D. $\(\left\)(fg\(\right\))\(\left\)(x\(\right\))=\(\sqrt{x}\]\left\)(x+17\(\right\))$, Domain: $\(\left\[\lbrack\)0,\(\infty\]\right\))$

Answer: (D)
