A new drone has the ability to fly over a body of water, dive underneath the water’s surface, return to the surface, and continue flying. The equation represents an observation of this maneuver, with respect to time, t
,
in seconds, and the drone’s height,
h
,
in feet, in relation to the surface of the water.
