If f(x)=x^(2) then the value of (f(1.1)-f(1))/(1.1-1)

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

If f(x) = x^5 - 1/x^5 then find the value of f(x) + f(1/x)

If 2f(x)+3f(-x)=x^(2)-x+1, find the value of f'(1)

If f(x+1/x)=x^2+1/x^2 then find the value of f(x)

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