Week 9—Graphing a Quadratic function

The basic representation of the quadratic function is y=ax squared +bx+c (a is not 0). The second function must be quadratic, and the graph of the quadratic function is a parabola that is parallel to the Y-axis or overlaps on the Y-axis.

The vertex coordinate intersection is

   (only the parabola with the intersection point with the X-axis),
