I gather you meant to say f( g(-2) )
The question said F over G and had (-2) next to it
OK ! We have : \[\frac fg(x)=\frac{f(x)}{g(x)}\]
$$ f(x) = −3x − 3\\ g(x) = 2x + 1\\ \cfrac{f(x)}{g(x)}\implies \cfrac{−3x − 3}{2x + 1} $$
So : \[\frac fg(-2)=\frac{f(-2)}{g(-2)}=\frac{-3(-2)-3}{2(-2)-1}=\frac{6-3}{-4-1}=\frac{3}{-5}\]
