A swim team member performs a dive in the pool from a springboard.
The parabola below shows the path of her dive. Use the graph to answer the sorting question below.



Sort each statement into agree or disagree (based on the graph above)

  • The diver’s height was
    decreasing the entire time.
  • The springboard was 14 feet high.
  • The diver reached her
    maximum height at 23 feet in the air.
  • The diver landed in the water about 14 feet away from the springboard.
  • The diver’s range was between 0 and 23 feet.
  • The diver is going up in the air
    between 0 < x < 3.
  • The diver was 4 feet away from the springboard when she reached her maximum height.
  • Between 3 feet from the springboard and 8 feet from the springboard, the diver’s height was decreasing.
  • When the diver was 5 feet away from the springboard, she was 19 feet high.
  • Using the graph, f(2) = 22.
  • The diver was again at the height of the springboard 6 feet away from the board.
  • The diver’s height was changing at a faster rate between 4 feet and 6 feet from the springboard versus 6 feet and 8 feet from the springboard.
  • Agree
  • Disagree
Question 9
9.

Match the statement to the quadratic equation it is describing.

  • My function's y-intercept and vertex are the same.
  • For my function, f(x) is negative when
    x < 0 and x > 2.
  • Find my function using the clue below:
    f(-1) + f(4) = -11
  • My minimum is y=1 and
    all the y-values of my function are positive.
  • The zeros of my parabola are (-6, 0) and (-2, 0).
  • My y-intercept is 5
    and my vertex is (-2, 1).
  • My function is decreasing over the interval (-4, ∞).
  • I have an axis of symmetry of x = -1.
  • My function is only increasing over the interval x > -1.
  • The range of my function is y ≤ 1.
  • The x-intercepts of my parabola are opposites.
  • My function has a vertex that is (0, 0) and an axis of symmetry of x = 0.
