Standard Form of a Quadratic Equation
f(x) = y = ax^2 + bx + c
Graphing Quadratics When In Standard Form
1) Find and graph the axis of symmetry using x = b/2a (think of b as "the opposite of b").
2) Find the ycoordinate of the vertex and plot the vertex on the coordinate plane.
3) Graph the yintercept (c) and its reflection.
4) Evaluate the function for another appropriate value of x. Graph the point and its reflection.
5) Once you have the vertex, two points to the left, and two points to the right, it is time to sketch the curve.
