Is there a specific way to determine the function of a given graph?if not, 
 
Then how will we solve the following question?
the accelaration – time graph of a particle is such that at t=0, a= -2, and at t=1, a=0. (I cant draw the graph so i am giving data deducable form graph)
(i) Find an expression of velocity in terms of t and draw v-t
(ii) Derive x9t) and hence calculate the displacement of the particle in the time interval from t=2 sec to t=4 sec
Assume that x=0,v=0 at t=0 ????
please help

							No not by the information you have given.
But try integrating the graph by intervals rather than taking initial to final.

							Now i have seen the attached image by you it wasn't coming before.
So,
from the graph we can say
a=2t-2;

Its quadratic equation you can draw its graph.
By the conditons given t=0 v=0 => c=0

again t=0 x=0; =>c=0

Rest you can do.
