Reflection in the x-axis and vertical stretch.

Front

Back

It causes the graph to open downward.

a=2, h=-4, k=-1

Front

Back

The vertex of the graph will move right 2 units.

Front

What is the vertex form of a quadratic equation?

Back

Front

What does the 'a' value in vertex form indicate about the graph?

Back

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

Front

How does a positive 'a' value affect the graph of a quadratic function?

Back

It opens upwards and the vertex is the minimum point.

Front

How does a negative 'a' value affect the graph of a quadratic function?

Back

It opens downwards and the vertex is the maximum point.

Front

What is the significance of the 'h' value in vertex form?

Back

The 'h' value represents the x-coordinate of the vertex and indicates horizontal shifts.
