"Linear function" means the highest degree of any term is 1.
Equation 1: degree is 2
Equation 2: degree is 2
Equation 3: degree is 1 . . . . this is your linear function
Equation 4: degree is 4
Answer:

Step-by-step explanation:
We are given the following in the question:
Quantity, q
Selling price in dollars per yard, p

Total revenue earned =

f(20)=13000
This means that 13000 yards of fabric is sold when the selling price is 20 dollars per yard.
f′(20)=−550
This means that increasing the selling price by 1 dollar per yards there is a decrease in fabric sales by 550.
We have to find R'(20)
Differentiating the above expression, we have,

Putting the values, we get,
