A machine is now worth $159,500 an will be depreciated linearly over a 9 years period, at which time it will be worth $43,760 as scrap.
a) Find the rule of depreciation function f?
b) What is the domain of f?
c) What will the machine be worth in 5 years?
___________________________________________________
a) f(x)=-115,740x+159,500
b) Domain should be from 0, 159500 to ??? (I don't know)
c)I used this formula: y=mx+b
First, I found m= 43,760-159,500/9-0=-115,740/9==12,860
Then y= - 12, 860(5)+159,500=-95,200
Is it -95,200 correct result? I'm not sure. Thank you for your help and explanation.

When no more than 110 units are produces, the cost of producing y unites is given by C(x)
C(x)=0.2x^3-25x^2+1504x+26,057
How many units should be produced in order to have the lowest possible average cost?
This is what I did:
I divided by x
0.2x^3/x-25x^2/x+1504x/x+26,057
Now, I put this on google search to get the graph but I have no idea how to find exactly the lowest number. So I move the line while Y decreasing right? And what I see, the lowest number is 62.5, but that's not correct answer. Can someone please explain me this part?
Thank you very much.
