denotes greatest integer less than or equal to x)
If f(1) = 1, f ^{1} (1) = 2, then
f is defined in [5, 5] as f(x) = x if x is rational = –x if x is irrational. Then
f(x) and g(x) are two differentiable functions on [0, 2] such that f ''( x)  g '' (x)= 0, f ' (1) =2g'(1)=4 f(2) =3g(2) = 9 then f(x)–g(x) at x = 3/2 is
