7. Ibrahim has designed an experiment for the National Oceanic and Atmospheric
Administration to measure temperature and wind speed at different altitudes. His measure
instruments have been attached to a weather balloon that was launched in the middle of
the Atlantic Ocean. The Mechanism holding the instruments to the balloon was designed
to let the instrument loose when the height of the balloon is exactly 85,000 feet above sea
level. The function f(x)represents the height (in feet) of the instruments exactly xseconds
after the instruments were released.
Translate the following statements into English sentences or phrases describing the situation. If

impossible to know.
a. f(0) = 85,000
b. f(9) > f (13)
c. f(10) = 0
