FLASHCARD QUESTION
Front
What are critical points in the context of quadratic inequalities?
Back
Critical points are the values of x where the quadratic expression equals zero. They are found by solving the equation ax² + bx + c = 0.

FLASHCARD QUESTION
Front
What does the symbol '≥' mean in a quadratic inequality?
Back
The symbol '≥' means 'greater than or equal to', indicating that the values satisfying the inequality can be equal to the critical points.

What does the symbol '<' mean in a quadratic inequality?
Back
The symbol '<' means 'less than', indicating that the values satisfying the inequality cannot include the critical points.

FLASHCARD QUESTION
Front
What is the significance of the parabola in quadratic inequalities?
Back
The graph of a quadratic inequality is represented by a parabola, which opens upwards or downwards depending on the sign of the leading coefficient (a). The regions above or below the x-axis indicate where the inequality holds.

Front
How do you determine the intervals for a quadratic inequality?
Back
After finding the critical points, test values from each interval created by these points in the original inequality to see if they satisfy the inequality.
