The profit from selling a certain oven is given by P(x)= -x^3-4x^2+80x
I found the actual profit from the sale of the 4th oven.
-4^3-4(4)^2+80(4)=$192
Then, it asks to use the marginal profit function to estimate the profit from the 4th oven and that is the part I don't know how to do. Please help.
