and where x is the middle value between the zeros.
Finding zeros using formula for general solution of quadratic equation:
D for discriminant,
Middle x between the zeros is
-
This means x=1 and y=4 is the maximum or "optimum" or VERTEX point for the function.
using the given original equation or function
