Identifying Parts of a Quadratic Function

Match the equation to its description.

• Stretched by 2 and up 4

• Compressed by 2 and up 4

• Stretched by 2 and left 4

• Compressed by 2 and left 4

When a parabola opens downward the vertex is

• a minimum

• a maximum

• a vertex

• a parabola

When a parabola opens upward the vertex is

• a minimum

• a maximum

• a vertex

• a parabola

How can you tell whether a parabola is facing up or facing down by looking at the equation?

• The vertex tells you the direction of the opening

• The value of "a" tells you the direction of the opening.

• All parabolas open upward

• All parabolas open downward
