A manufacturer has determined that the price depends on the weekly demand based on the following function: p = f(q) = 10 – q² where p is the unit price and q is measured in units of a thousand (q = 1 means 1000 units). (a) Find the average rate of change in the unit price when the quantity demanded is between 1000 and 2000. (b) Find the average rate of change in the unit price when the quantity demanded is between 1000 and 1100. (c) Using limits, find the instantaneous rate of change in the unit price at the quantity 1000. No marks for using derivative rules (Section 4.3 and later).

Question
A manufacturer has determined that the price depends on the weekly demand based on the following
function:
p = f(q) = 10 – q²
where p is the unit price and q is measured in units of a thousand (q = 1 means 1000 units).
(a) Find the average rate of change in the unit price when the quantity demanded is between 1000 and
2000.
(b) Find the average rate of change in the unit price when the quantity demanded is between 1000 and
1100.
(c) Using limits, find the instantaneous rate of change in the unit price at the quantity 1000. No marks
for using derivative rules (Section 4.3 and later).
