• Question 2
300 seconds
Q. Pablo throws a ball with a path of
h = -5(t - 2)2.
Maria throws a ball with a path of
h = -5(t - 2)2 + 10.
Which description is reasonable for the difference in the two equations?
Maria throws the ball 10 times harder than Pablo does.
Maria starts her ball at a height 10 feet higher than Pablo does.
Pablo throws the ball 10 times harder than Maria does.
Pablo starts his ball at a height 10 feet higher than Maria does.

• Question 11
120 seconds
Q. Which list orders the quadratic functions from narrowest to widest?
y = x2
y = 4x2
y = 2x2 - 2
y = 0.5 x2
y = 0.5 x2
y = x2
y = 2x2 - 2
y = 4x2
y = 4x2
y = 2x- 2
y = x2
y = 0.5 x
y = 2x2 - 2
y = 4x2
y = 0.5x2
y = x2
