Question

A model rocket is launched straight up. Its height in feet (y) above the

ground x seconds after launch is modeled by the quadratic function: y=
-16x2 + 216x + 6.
How many seconds did it take the rocket to reach its maximum height?

Answer 1

ground x seconds after launch is modeled by the quadratic function: y=

-16x2 + 216x + 6.
