Answer:
f(x) = x^4/12 + 8x + 4
Step-by-step explanation:
f"(x) = x^2
Integrate both sides with respect to x
f'(x) = ∫ x^2 dx
= (x^2+1)/2+1
= (x^3)/3 + C
f(0) = 8
Put X = 0
f'(0) = 0+ C
8 = 0 + C
C= 8
f'(x) = x^3/3 + 8
Integrate f(x) again with respect to x
f(x) = ∫ (x^3 / 3 ) +8 dx
= ∫ x^3 / 3 dx + ∫8dx
= x^(3+1) / 3(3+1) + 8x + D
= x^4/12 + 8x + D
f(0) = 4
Put X = 0
f(0) = 0 + 0 + D
4 = D
Therefore 
f(x) = x^4 /12 + 8x + 4

<u>Given </u><u>:</u><u>-</u>
- A dealer sold a photocopy machine at Rs 4200 with 13% VAT to a retailer.
- The retailer added transportation cost of Rs 250 , profit Rs 300 and local tax Rs 150 and sold to consumer . 
- Customer has to pay 13% VAT .
<u>To </u><u>Find </u><u>:</u><u>-</u>
- Amount to be paid by the customer .
<u>Sol</u><u>u</u><u>tion </u><u>:</u><u>-</u>
Here , according to the question ,
 
 
 
 
Therefore cost after adding VAT ,
 
 
 
 
 
 
 
 
Again the values added by the retailer before selling to customer ,
- Transport = Rs 250
- Profit = Rs 300
- Tax = Rs 150 
Therefore total cost after adding these , 
 
 
 
 
Again Selling price after addition of 13% VAT ,
 
 
 
 
 
 
 
 
<u>Hence </u><u>the </u><u>amount </u><u>to </u><u>be </u><u>paid </u><u>by </u><u>the </u><u>customer </u><u>is </u><u>Rs </u><u>6</u><u>1</u><u>5</u><u>4</u><u> </u><u>.</u>
 
        
                    
             
        
        
        
Daniela made her error on step 3 because it says: 
"Find the ratio of the differences of the means compared to the mean absolute deviation.
She didn't find the difference between the today and last week means. She just put the mean as a whole.
