Front

What does the vertex of a parabola represent?

Back

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

Front

What is the difference between a maximum and a minimum in the context of quadratic functions?

Back

A maximum is the highest point on the graph of a downward-opening parabola, while a minimum is the lowest point on the graph of an upward-opening parabola.

Front

How do you determine the range of a quadratic function?

Back

The range of a quadratic function depends on the vertex. If the parabola opens upwards, the range is from the y-coordinate of the vertex to infinity. If it opens downwards, the range is from negative infinity to the y-coordinate of the vertex.

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

Back

The x-intercepts can be found by setting the quadratic equation equal to zero and solving for x, either by factoring, using the quadratic formula, or completing the square.
