Answer:
I am not 100% sure but my best guess would be the object is moving backwards/falling.
Step-by-step explanation:
The graph shows the position of the object going from almost 9.0 to below zero. There are many situations that could fit this. Such as, something going above and below sea level. OR something moving in front and behind a certain point. My best guess would be moving backward towards an object OR falling from a certain point.
