How do you find the x-intercepts of a quadratic function?

Back

To find the x-intercepts of a quadratic function, set the function equal to zero and solve for x. The solutions are the points where the graph intersects the x-axis.

What does it mean for a quadratic inequality to be greater than zero?

Back

A quadratic inequality being greater than zero means that the values of the quadratic expression are positive. This typically indicates the regions of the graph that lie above the x-axis.

What is a parabola?

Back

A parabola is the graph of a quadratic function. It is a U-shaped curve that can open upwards or downwards depending on the sign of the leading coefficient (a) in the quadratic equation.

Front

What does it mean for a quadratic function to be less than zero?

Back

A quadratic function being less than zero means that the values of the quadratic expression are negative. This indicates the regions of the graph that lie below the x-axis.

Front

How do you determine the solution set for a quadratic inequality?

Back

To determine the solution set for a quadratic inequality, first find the x-intercepts by solving the corresponding quadratic equation. Then test intervals between the x-intercepts to see where the inequality holds true.
