Determine the quadratic function whose graph is given.
-If a rocket is propelled upward from ground level, its height in meters after t seconds is given by h = -9.8t² + 117.6t. During what interval of time will the rocket be higher than 343 m?

Question

Quizplus · Accepted Answer

To find when the rocket is higher than 343 m, we set the height equation greater than 343: -9.8t^2 + 117.6t > 343. Solving this quadratic inequality, we find the time intervals when the rocket's height exceeds 343 m. The correct interval, after solving, is between 5 and 7 seconds.
