A relief organization flew over a village and dropped a package of food and medicine. The plane is flying at 1000 feet. The function h = –16t2 + 1000 gives the package’s height h above the ground (in feet) after t seconds. Graph the function. How many seconds does it take for the package to hit the ground?

At which value in the domain does f(x) =0?
