<h3>Answer: B) $878.28</h3>
================================================
Explanation:
She starts off $16.75 in debt
Later on she deposits $16.75 to get completely out of debt and make the balance 0. This is after depositing the $5.72
So far her balance is $5.72
Add on $872.56 to get 5.72+872.56 = 878.28
-------------
This is what your steps may look like
-16.75 + (5.72 + 16.75)
-16.75 + (16.75 + 5.72)
(-16.75+16.75) + 5.72
(0) + 5.72
5.72
5.72+872.56
878.28
 
        
        
        
Domain is [-10,∞) 
2 is included , only at x=2 new function begins
Range is the values of y , so range  is [-7]∪[-4,6
I think, it should be  like this.
