6. An osprey, a fish-eating bird of prey, dives towards the water after a salmon. The height (h), in meters, of the osprey above the water (t) seconds after it begins its
decent can be approximated by the function f (t) = 4+241 +36 , where
h=f(t). After how many seconds does the osprey reach the water?
After
seconds the osprey will reach the water.
