Determining on what type of Motion to use on a Position Time Graph?

[kencamarador]

I was given a table to plot on to a position time graph, but how would I know what type of motion to use? A curve or straight line?

Here is the table

T---P


0---0.0
4---2.0
6---3.0
10---4.0
15---5.0
16---5.0
18---4.4
22---3.2
26---2.0
28---1.4
33---0.0
