A roller coaster is being designed that starts at LaTeX: \left(0,22\right) and ends at LaTeX: \left(19,2\right). Along the ride there is a relative minimum at LaTeX: \left(5,6\right) and a relative maximum at LaTeX: \left(10,18\right). The roller coaster is almost finished but one section is missing. Find the correct function that completes the roller coaster so that the ride is smooth and continuous.
