The function f(x)=-2x^2+12x+32 models the approximate height of an object t seconds after it is launched. How many seconds does it take the object to hit the ground?
------------
There's no t in f(x)
Using x for the seconds:
---
It hits the ground when f(x) = 0
-2x^2+12x+32 = 0
Solve for x.
Ignore the negative solution.
