Question 1053227
The height h in feet of a Frisbee thrown is given by h(x)=x-0.099x^2+3, where x is the time traveled in seconds.  The Frisbee is released at a height of 3 feet.  At what time will the height of the Frisbee be 3 feet again?
------------
When h(x) = 3
---
h(x)=x-0.099x^2+3 = 3
x - 0.099x^2 + 3 = 3
It's a quadratic.
Solve for x.
