  1. Graphing Quadratic Inequalities of Parabolas Opening Up
    Graph:
    i) y=13x223x83y = \frac{1}{3}{x^2} - \frac{2}{3}x - \frac{8}{3}
    ii) y13x223x83y \ge \frac{1}{3}{x^2} - \frac{2}{3}x - \frac{8}{3}
    iii) yy < 13x223x83\frac{1}{3}{x^2} - \frac{2}{3}x - \frac{8}{3}
    1. Graphing Quadratic Inequalities of Parabolas Opening Down
      Graph:
      i) y=x24xy = - {x^2} - 4x
      ii) yy > x24x - {x^2} - 4x
      iii) yx24xy \le - {x^2} - 4x
