**Step 1. Compute $$ (q \circ r)(-4) $$:**  
We have  
$$
r(x)=-x-5 \quad \text{and} \quad q(x)=2x-2.
$$  
First, find $$ r(-4) $$:  
$$
r(-4)=-(-4)-5=4-5=-1.
$$  
Now, compute $$ q(r(-4))=q(-1) $$:  
$$
q(-1)=2(-1)-2=-2-2=-4.
$$  
Thus,  
$$
(q \circ r)(-4)=-4.
$$

**Step 2. Compute $$ (r \circ q)(-4) $$:**  
First, find $$ q(-4) $$:  
$$
q(-4)=2(-4)-2=-8-2=-10.
$$  
Now, compute $$ r(q(-4))=r(-10) $$:  
$$
r(-10)=-(-10)-5=10-5=5.
$$  
Thus,  
$$
(r \circ q)(-4)=5.
$$
$$ (q \circ r)(-4) = -4 \quad \text{and} \quad (r \circ q)(-4) = 5 $$
