Equation h(t) = -5+ ²+ 30t gives the height
in meters above the ground after t second's of a throw rock.
The rock is thrown from a window of a building
that is
O meters above the ground. The upwand
velocity of the rock is 30 sec. Complete the table of
values and a graph of the entire vertical flight of the rock,
