Which Parabola will open upward and be wider than the graph of y=x²?

• y=5x² - 3
• y=4x²+7
• y=-½x²-1
• y=¼x² - 5

Which of the following equations describes the quadratic parent function, y=x², after it has been reflected across the x-axis and shifted down 2 units?

• y=x²-2
• y=-x²-2
• y=x²+2
• y=-x²+2

Which of the following equations would make y=x² narrower?

• y=x²+5
• y=-x²
• y=5x²
• y=0.5x²

How would the graph of y=x²-5 be affected if the function were changed to y=x²+3

• The graph would shift up 8 units
• The graph would shift down 8 units
• The graph would shift to the left 2 units
• The graph would shift to the right 2 units

Which list orders the quadratic functions from narrowest to widest?

• y = 4x²

  y = x²

  y = 2x² - 2

  y = 0.5 x²

• y = 0.5 x²

  y = x²

  y = 2x² - 2

  y = 4x²

• y = 4x²

  y = 2x² - 2

  y = x²

  y = 0.5 x²

• y = 2x² - 2

  y = 4x²

  y = 0.5x²

  y = x²

Does y = -4x² have a maximum or minimum value?

• maximum
• minimum
