A small marshmallow is launched straight up in the air with a
slingshot. The function h, given by the equation h(t) = 5+20t-5t2, describes the
height of the marshmallow in meters as a function of time, t, in seconds since it was
launched.
a. Use graphing technology to graph the function h.
b. About when does the marshmallow reach its maximum height?
c. About how long does it take before the marshmallow hits the ground?
d. What domain makes sense for the function h in this situation?
