Write your own quadratic equation in the standard form, f(x) = a * x ^ 2 + bc + c such that a, b, and c do not equal zero . For example , x ^ 2 - 9x + 18; x ^ 2 + 5x + 4 Describe at least two methods that can be used to determine the graph of your function.

Find the maximum or minimum value (HINT: think: vertex). Explain how you can
determine this value. x=-b/2a

Write your quadratic equation in vertex form.

Determine the zeros of your function.
