1. Matching Puzzle Grab a pair of scissors, a puzzle sheet and sit at your desk.

2. Warm up: Write the WHOLE problem down. 1.The data below represents the height of a rocket shot from 150 ft above ground and traveling at a velocity of 50 m/second. Find the quadratic equation that models this data. 2. What form of the quadratic equation did we get from this data? Seconds012345 Meters150195.1230.44255.9271.6277.5

3. Answer:

4. Follow up Now find the maximum height reached by the rocket, and how many seconds it took to get there. In order to answer this question we need to know the______? Can we determine the vertex given the general equation? What form to we need?
