A quadratic inequality is an inequality is an inequality whose highest exponent on its variable is 2. The graph of a quadratic inequality is similar to the graph of a quadratic equation with the region inside or outside the parabola shaded. To graph a quadratic inequality, we express the quadratic inequality as a quadratic equation and convert the equation to the vertex form. With our knowledge of graphing quadratic equations, we can graph the quadratic equation. Next, we choose a point inside the parabola and a point outside the parabola and test which of the points satisfy the original quadratic inequality. Then we shade the portion that satisfies the quadratic inequality.\n
