Expert Answer:

The displacement x(t) = 4 + 2×t - t2
 
Table given below shows the position and displacement fro t=0 to t=2
 
t      x(t)        displacement
                     in 1 s
----------------------------------
0       4             ------
1       5               1
2       4              -1
