Front

What effect does the coefficient of a quadratic function have on its graph?

Back

The coefficient affects the width and direction of the parabola. If 0 < a < 1, the graph becomes wider (vertically compressed). If a > 1, the graph becomes narrower (vertically stretched).

What is the parent function of a quadratic equation?

Back

The graph is shifted down by 4 units.

Front

What does it mean for a graph to be reflected over the x-axis?

Back

It means that for every point (x, y) on the graph, the point (x, -y) is also on the graph.

What is the effect of a negative coefficient in front of a quadratic function?

Back

It reflects the graph over the x-axis.

Front

If a quadratic function is stretched by a factor of 2, what happens to its graph?

Back

The graph becomes narrower.

Front

What does it mean for a graph to be vertically compressed?

Back

It means that the graph is wider than the parent function, indicating a coefficient between 0 and 1.

Front

How can you identify a vertical stretch in a quadratic function?

Back

If the coefficient a > 1, the graph is vertically stretched and becomes narrower.
