$(f\°g)(-2)=-5$

Step-by-step explanation:

The first step is substitute the function $g(x)=\sqrt{(x+3)}$ into the function f(x)=-7x+2

$(f\°g)(x)=-7(\sqrt{(x+3)})+2\\(f\°g)(x)=-7\sqrt{(x+3)}+2$

Now, you need to substitute x=-2 into $(f\°g)(x)=-7\sqrt{(x+3)}+2$ and simplify the function.

Finally you get that $(f\°g)(-2)$ is:

$(f\°g)(-2)=-7\sqrt{(-2+3)}+2\\(f\°g)(-2)=-7\sqrt{1}+2\\(f\°g)(-2)=-7(1)+2\\(f\°g)(-2)=-7+2\\(f\°g)(-2)=-5$
