    Does anyone know how to find the answer to the following question?:
    A quadraticprofit function in N, where N is the number of items, has break even pointsN=250 and N = 3150. For what value of Ndoes the maximum profit occur?

    Any help would be appreciated ^^

    What does it mean in terms of coordinates for a break even point? Can you then construct a quadratic with those two points? (hint: roots, (x-a)(x-b)) can you then expand this, differentiate and find the maximum point?

    Or line of symmetry is halfway between each of the roots. You can't actually find the maximum profit as 2 roots of a quadratic is not enough information to go off. But you can find the value of N as it will be half way between the 2 roots.
