Find the maximum yield function from the given data
An apple tree produces, on average, 400Kg of fruit each season. However, if more than 200 trees are planted per , crowding reduces the yield by 1 Kg for each tree over 200.(a) Express the total yield from one square Kilometer as a function of the number of trees on it. Graph this function.(b) How many trees should a farmer plant on each square Kilometer to maximize yield?
