The domain, since t<0 has no real context, is from zero to the time, t, when the height is equal to zero. Height equals zero when:
-5t^2+20t+50=0 using the quadratic equation for simplicity:
t=(-20±√1400)/-10, since t>0 when h=0
t=(-20-10√14)/-10
t=2+√14 seconds
t≈5.74 seconds
So the domain is:
t=[0, 2+√14]
t≈[0, 5.74] (to the nearest hundredth of a second)
