The approximate height,
h, in metres, of an object above the ground after
it is dropped from a distance,
d, in metres, can be modelled by the function

, where
t is the time, in seconds, after being dropped.
a) Determine the function for an
object being dropped from each height.
i) 400 m
ii) 550 m
iii) 850
m
b) Graph all three functions on the same set of axes.
c) Describe the
transformation that relates the highest curve to the lowest curve.
d) Describe the
transformation that relates the highest curve to the curve in the middle.
