Asked by JB
A stone is thrown skyward from the top of building. The distance in feet between the stone and the ground in 't' seconds is given by the function h (t) = -16t(t) -4t+ 442. How long after the stone is thrown is it 430 feet from the ground?
Sorry I don't know how to type t squared.

just solve
-16t^2 + 4t + 442 = 430
Your equation, with -4t, has the stone being thrown downward. It seems to be at odds with the skyward initial toss.
