A rollercoaster track consists of a series of vertical curves.
Near the top of one of these curves, the track enters a tunnel, where passengers ride in
the dark for a short duration. The parabola in the graph represents the rollercoaster
track,
The vertex of this parabola is at (7.5. 21), and another point on the track is at (0.9).
A steel beam is part of the supporting structure of the rollercoaster track. The beam is
attached to the framework at the points (0.12) and (12, 19). determine the two equations of the parabola (quadratic function) and line
