Going Beyond

 

Suppose you chose the end of the parabola to be on the y-axis. This would mean that the vertex would no longer be at the origin. The quadratic function would be slightly different, but you should arrive at the same final answer. How would that change the calculation?

 

Look at how the problem from Self-Check 4 has been redrawn to have the end of the parabola at the origin.



 
This image shows the parabolic path a kicker kicks a ball with a horizontal distance from the origin of 126 meters and the ball risen to a height of 22 metres. The first sketch shows the coordinate grid with the origin at the vertex of the parabola, and the second sketch has the end of the parabola where the ball hits the ground as the origin.
  1. Use the new drawing to answer the questions from Self-Check 4.

  2. Do you arrive at the same answer?

  3. What steps were you able to eliminate that were in the previous solutions?
