Front

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

Back

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

Front

How do you determine 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.

Front

What is the significance of the vertex in a quadratic function?

Back

The vertex represents the maximum or minimum point of the parabola, depending on whether it opens upwards or downwards.

Front

What does it mean if the vertex is at its minimum?

Back

If the vertex is at its minimum, the parabola opens upwards, and the vertex is the lowest point on the graph.
