Ppt Recall The Graph Of A Quadratic Function Y Ax 2 Bx C Is A Parabola Powerpoint Presentation Id If you don't see an x 2 term, you don't have a quadratic equation!The graph of a quadratic equation in two variables (y = ax2 bx c) is called a parabola The following graphs are two typical parabolas their xintercepts are marked by red dots, their yintercepts are marked by a pink dot, and the vertex of each parabola is marked by a green dot We say that the first parabola opens upwards (is a U shape) and the second parabola opens Y ax 2-bx+c
