73.

a)


b)
Since we can't divide by zero, we need to find when:

But before, we can factor the numerator and the denominator:

Now, we can conclude that the vertical asymptotes are located at:

so, for x = -3:


For x = 4:

 
 
        
             
        
        
        
Answer:
$4000
Step-by-step explanation:
so $2800 was the starting price
100%-30%=70%

2.86-2.81=0.05
(0.05/3.86)x100=1.75%
