An object is attached to a coiled spring. The object is pulled down 9 cm from its rest position and then it is released. It takes 3 seconds for the object to travel from its lowest position to its highest position. Write an equation to model how the distance of the object from its rest position (in cm)  changes with time (in seconds).

What is another name for a phase shift?

• Horizontal Dilation

• Horizontal Shift/Translation

• Vertical Dilation

• Vertical Shift/Translation
