The xy-coordinate plane is given. A curve has a cycle that repeats horizontally every 23.One cycle starts on the y-axis at y =3.5, goes down and right becoming more steep, crosses the x-axis at x =6, goes down and right becoming less steep, changes direction at the point (3,3.5), goes up and right becoming more steep, crosses the x-axis at x =2, goes up and right becoming less steep, and stops at the point (23,3.5).The next cycle starts at x =23.Find the amplitude and period.
