Graph Quadratics Using Vertex Form

Does the quadratic have a maximum or minimum vertex, and does the parabola open up or down?

• max/ opens down

• min/ opens up

• max/ opens up

• min/ opens down

Is this a max or min?

• max

• min

• cannot be determined

How many zeros does this parabola have? 

• 3

• 2

• 0

• 1

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

Graph -(x + 5)² + 5.

You can drag one dot to the vertex and another to another point on the parabola.

Graph -3(x - 4)² + 1.

You can drag one dot to the vertex and another to another point on the parabola.
