Quadratic Property Review

What is another word for zeros?

• y-intercepts
• roots
• vertex
• axis of symmetry

What is another word that describes the zeroes of a quadratic function?  

• y-intercepts
• vertex
• x-intercepts
• maximum

What is the arrow pointing at? How can you use this value to determine the minimum/maximum values?

• The arrow is pointing at the y-intercept. 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
• 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 y value is equivalent to the minimum/maximum

What is the vertex?

• (4,-4)
• (2,0)
• (0,2)
• (6,0)

What is the axis of symmetry?

• x = - 4
• x = - 2
• x = 0
• x = 4

Does the equation open up or down? 
Y = -3x² +7x - 2

• up
• down

Determine the interval of this functions DOMAIN.

• (-∞, 2)
• No Solution
• (-∞, ∞)
• (-∞, 1)

What are the solutions?

• 0 and 8
• -2 and -4
• 3 and -1
• 2 and 4

Solve by factoring.
z² - 18z + 81 = 0

• z = 9
• z = -9
• z = 9 or z = -9

What is this?

• This is the speed of light formula.
• This is the quadratic formula.
• This is the zero product property.
• This is scary.
