What are the tables for
f (x) = 2x1
f (x) = [[x]] + 3
f (x) = x2
f (x) = 2 [[x1]]
f (x) = [[x]]2
f (x) = 2 [[x+1]]

You mean table of values? You compute them, goodness.
take f(x)=abs(x2). Put in values for x, and compute, and tabulate it.
x.....f(x)
0.....2
1.....1
3....5
100...98
100..102
and so on.
