You now have learned 3 different variations to graphing a quadratic equation.
Imagine after learning standard form you got bored and drooled on the desk while I presented vertex
form and intercept form (I know…bored with math…impossible). Given an equation in vertex form, how
could you use what you know to graph the function?
Write the quadratic function in standard form.
