Properties of Graph

If the a value is negative, which direction does the parabola open?

• up
• down
• left
• right

If the a value is positive, which direction does the graph open?

• up
• down
• left
• right

Does this graph have a maximum or minimum?

• Minimum
• Maximum

What is the green dot on the parabola called?

• maximum
• minumum
• roots
• zeros

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

Is this a max or min?

• max
• min
• cannot be determined

Does this parabola have a minimum or maximum and what is its value?

• minimum: 2
• maximum: 2
• minimum: 5
• maximum: 5

Determine if the function graphed has a maximum or a minimum value and identify that value.

• maximum at -1

• minimum at -1

• maximum at 4

• minimum at 4
