Find the value of f ( 0 ) + f ( 1 )
f ( x ) = `x^3 + x`

Find the value of f(f(-2)) , if f(x)=(x)/(x+1)

Ilf f(x)={x^3, x 2 , then find the value of f(-1)+f(1)+f(3) . Also find the value (s) of x for which f(x)=2.

Find the value of f(0) so that the function.f(x)=(sqrt(1+x)-root(3)(1+x))/(x) becomes continuous at x=0

If f (x) is continous on [0,2], differentiable in (0,2) f (0) =2, f(2)=8 and f '(x) le 3 for all x in (0,2), then find the value of f (1).

If f(x)=x^(2+x+1 , then find the value of 'x' for which f(x-1) =f(x)

If f(x) = 1/( 1 - x ) , find the value of f[ f ( f(x) ) ]

If f'(3)=8 then the value of Lt(x → 0)(f(3+x)-f(3-x))/(2x)=

If f(x ) = x^3 - 1/x^3 , then find the value of f(x) + f( 1/x )
