Use the quadratic formula to solve the equation. If necessary, round to the nearest
hundredth.
A model rocket is launched from a roof into a large field. The path of the rocket can be
modeled by the equation y = -0.04x4 + 8.3x + 4.3, where x is the horizontal distance, in
meters, from the starting point on the roof and y is the height, in meters, of the rocket
above the ground. How far horizontally from its starting point will the rocket land?
