What are the X-intercepts of a quadratic function?

Back

The X-intercepts are the points where the graph of the quadratic function crosses the X-axis, represented as (x, 0).

Front

What is the maximum or minimum value of a quadratic function?

Back

The maximum or minimum value of a quadratic function occurs at the vertex. If the parabola opens upwards, it has a minimum value; if it opens downwards, it has a maximum value.

How can you find the X-intercepts of a quadratic equation?

Back

To find the X-intercepts, set the quadratic equation equal to zero and solve for x using factoring, completing the square, or the quadratic formula.
