Use graphing technology to answer the following questions. Round to two decimal places when needed.
From a clifftop over the ocean above sea level, an object was shot straight up into the air with an initial vertical speed of . On its way down it missed the cliff and fell into the ocean. Its height (above sea level) as time passes can be modeled by the quadratic function , where . Here represents the number of seconds since the object’s release, and represents the object’s height (above sea level) in meters.
(Use
m for meters, and
s for seconds.)
