Introduction to Vertex Form

Is this a max or min?

• max

• min

• cannot be determined

What is the green dot on the parabola called?

• maximum

• minumum

• roots

• zeros

What is the vertex of the graph. Is it a maximum or minimum?

• (0,0) maximum

• (0,0) minimum

• (2, -1) minimum

• (2, -1) maximum

What is the green dot on this parabola called?

• vertex

• top of the mountain

• tip of the iceberg

• peak of the parabola

What is the vertex of this parabola?

• (−1, 3)

• (−3, 11)

• (−2, 5)

• (0, 5)

Does this parabola have a maximum or minimum?

• Maximum

• Minimum

What is the arrow pointing at? How can you use this value?

• The arrow is pointing at the y-intercept. The x-value is the axis of symmetry and the y-value of this point is equivalent to the maximum/minimum 

• The arrow is pointing at the vertex. The x value of this point is equivalent to the maximum/minimum and the y-value is the axis of symmetry

• The arrow is pointing at the solution. The y value of this point is equivalent to the maximum and the x value is equivalent to the minimum

• The arrow is pointing at the vertex. The x-value is the axis of symmetry and the y-value is equivalent to the minimum/maximum

The axis of symmetry line passes through which point?

• y-intercept

• any random point

• vertex

• none of these

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

• (-1, 4); opens up

• (-1, 4); opens down

• (1, 4); opens up

• (1, 4); opens down

What is the equation for axis of symmetry?

• y=3

• x=3

• x=5

• x=1
