D. (5,-21) would be your answer 
 
        
             
        
        
        
Given:
PV = 13,440
i = 5.86% , compounded monthly
t = 4 years
13,440(0.0586/12))/(1-(1+0.0586/12)^-48= 15,109.44 
15,109.44 + 156.60 = 15,266.04 
15,266.04 - 13,440.00 =  1,826.04 
<span>1,826.04/15,266.04 = 11.96 % Percentage total of Finance Charge of the total loa</span>
        
                    
             
        
        
        
A.)|−60 − 13| = |−73| = 73 units is the answer
 
        
             
        
        
        
Assuming I understand your question correctly, in that you’re looking for just some descriptions of the differences between the functions. If so, then I’d say:
First graph both functions, the f(x) and the g(x). Then spot the differences. 
Note that the g(x) function has shifted towards the right compared with the f(x) function. 
Another way that the g(x) differs from the f(x) function is that it’s stretched. The vertex is in the IV quadrant for g(x) rather than at the origin for f(x).
I hope that helps.
