A(x)=x(400-x), where x is the width of the pen. Is A(x) a quadratic function?
--------------------------------------------------------------------
Obviously yes.
--------------------------------------
What is the maximum area of the pen?
-------------------------------------
roots 0 and 400, exact middle being 200 for x.
Maximum area
