How do you determine if a point is a solution to a quadratic inequality?

Back

To determine if a point is a solution, substitute the x and y values of the point into the inequality. If the inequality holds true, then the point is a solution.

What is the significance of the y-intercept in a quadratic inequality?

Back

The y-intercept is the point where the graph of the quadratic function intersects the y-axis, which helps in sketching the graph of the inequality.

What is the vertex of a parabola represented by a quadratic function?

Back

The vertex of a parabola is the highest or lowest point on the graph, depending on whether it opens upwards or downwards.

How do you graph a quadratic inequality?

Back

To graph a quadratic inequality, first graph the corresponding quadratic equation as a solid line (for ≤ or ≥) or dashed line (for < or >), then shade the appropriate region based on the inequality.
