If f(x) = x + 1/x , then which of the following is correct?
[ f (x) ]^{3} = f (x)^{3} + 3 f (x)
[ f (x) ] 3 = f (x)^{3} - 3 f (1/x)
[ f (x) ]^{3} = f (x ^{3} )+ 3 f (1/x)
f (x)^{3} = (f [x])^{3} - 3 f (x)
The polynomial function f (x) of the second degree when f (0) = 4 is
a^{2} + bx + c = 4
c = 4
a = 4
b = 4
If f (1 + x) = x^{2} + 1, then f(2 - h) =
