The parabola below shows the path of her dive. Use the graph to answer the sorting question below.
1

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
If you finish the sorting and have reasons for each decision, try predicting the characteristics of this soccer ball kick on desmos. You can use the graph and/or the equation.
