Front

What is the vertex of a parabola?

Back

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

Front

What does the 'a' value in the quadratic equation affect?

Back

The 'a' value determines the direction of the parabola (upward if a > 0, downward if a < 0) and its width.

Front

What is the general shape of a parabola?

Back

A parabola is a U-shaped curve that can open upwards or downwards.

Front

What is the effect of changing the 'c' value in a quadratic function?

Back

Changing the 'c' value shifts the graph up or down without affecting its shape.

Front

What is the difference between a maximum and minimum value in a quadratic function?

Back

A maximum value occurs at the vertex if the parabola opens downward, while a minimum value occurs if the parabola opens upward.
