Quadratics

The graph of a quadratic function is called a

• Parabola
• Vertex
• Axis of Symmetry 
• Vertex Form

Does the graph of the function

y = -2(x + 5)² + 2

have a minimum or a maximum?

• Minimum

• Maximum

• It has neither.

• It has both.

What is the range of the function?

• y < -1

• y > -1

• y < -2

• y > -2

Identify the vertex and whether the graph opens up or down.

• (5, 2); opens up

• (5, 2); opens down

• (-5, 2); opens up

• (-5, 2); opens down

What is the green dashed line called?

• roots or x-intercepts

• y-intercept
• any random point
• vertex
• symmetrical point for the vertex

A parabola has a vertex at (-3,2).

Where is the axis of symmetry?
