WebWe need to find the value of x that makes A as large as possible. A is a quadratic function of x, and the graph opens downward, so the highest point on the graph of A is the vertex. Since A is factored, the easiest way to find the vertex is to find the x-intercepts and average. 2x (400 -4x/3) = 0. 2x = 0 or 400 -4x/3 = 0. x = 0 or 400 = 4x/3. http://dl.uncw.edu/digilib/Mathematics/Algebra/mat111hb/PandR/quadratic/quadratic.html
