4. A falcon is flying from the top of a tree to the top of an old farm’s roof in order
to catch a pigeon. Its flying trajectory is a parabolic shape modeled by
!
+ 10, where ℎ and are measured in meters.
ℎ() = −5( + 6)
Part A: Identify the vertex of the function.
Part B: If the falcon is at a height of 20 meters, how far away is the tree from
the old farm’s roof?
