The graph shows the height of a rocket over time. What conclusion can be made about the flight of the rocket?

• The rocket reached its maximum height at 4 seconds.
• At 0 seconds, the rocket was 3 meters off the ground.
• The rocket was in flight for 16 seconds.   
• The maximum height of the rocket was 8 meters.

How would you describe the translation from f(x)=x² to f(x)=(x+3)² ?

• Horizontal translation: three units to the left

• Horizontal translation: three units to the right

• Vertical translation: three units up

• Vertical translation: three units down

Which quadratic is the narrowest graph?

• y = 3x²
• y = 4x²
• y = 2x²

If the blue graph is
f(x) = x² 
then the red must be...

• g(x) = x² - 5
• g(x) = x² + 5
• g(x) = (x - 5)²
• g(x) = (x + 5)²

What are the zeros for the quadratic function? 

• (-6, 0) and (14, 0)
• (-50, 0) and (14, 0)
• (-6, 0) and (-50, 0)
• (-50, 0) and (-60, 0)

Factor: x² - 10x + 24

• (x + 4)(x - 6)

• (x + 2)(x - 12)

• (x - 2)(x - 12)

• (x - 4)(x - 6)

Factor completely.
 $x^2\ -\ 8x\ -20$  

• (x + 10)(x - 2)

• (x + 5)(x - 4)

• (x + 2)(x - 10)

• (x + 4)(x - 5)

What is the vertex form of a quadratic function?

• f(x) = 2a(x - h)² + k

• f(x) = a(x - h)² + k

• f(x) = (x + h)² + k

• f(x) = a(x - h) - k

In the vertex form f(x) = a(x - h)² + k , what does the 'a' value do?

• Shifts the function left or right

• Changing 'a' value has no affect on the parent function

• Vertical stretch or compression

• Shifts the function up or down
