Question
Suppose the marginal profit from the sale of x hundred items is:
P'(x)=4-6x=3x^2
and the profit of 0 items is -$40
A. Find the profit function.
B. Find the profit from selling 800 items
I assume the P' is 4-6x+3x^2
Then P= 4x - 3x^2 + x^3 + C
where C is the constant of integration. You have P when x=0, so C= -40
Put in x=800 and you have it.
