RUNNING The table shows how wind affects a runner’s performance in the 200 meter dash. Positive wind speeds correspond to tailwinds and negative wind speeds correspond to headwinds. The change in t in finishing time is the difference between the runner’s time when the wind speed is s and the runner’s time when there is no wind.
Use the given data and a graphing calculator to find the best-fitting quadratic model.
Wind speed
(m/sec), s
-6 -4 -2 0 2 4
Change in finishing time (sec), t
2.28 1.42 0.67 0 -0.57 -1.05
