Find the indicated function and write its domain $in$ interval notation.

$f(x)=\frac{3}{x^2-16},g(x)=\sqrt[\phantom{2}]{6-x},(f$@$g)(x)=$

Select one:

$A.\frac{3\sqrt[\phantom{2}]{6-x}}{x^2-16}$;$(-,4)(4,6]$

$B.-\frac{3}{x+10}$;$(-,-10)(-10,)$

$C.-\frac{3}{x+10}$;$(-,-10)(-10,6]$

$D.\frac{3\sqrt[\phantom{2}]{6-x}}{x^2-16}$;$(-,4)(4,)$
