If f'( x ) = `1/x + x `, and f(1 ) = `5/2` then find f(x)

If f'(x)=x/2 + 2/x and f(1)=5/4 , then find f(x) .

If f(x-1)=x^(2) , then find f(x+1)

if f(x)=1/(1-x) then find f((x-1)/x)

f(x)+f(1-x)=2 then find f((1)/(2))=

let f(x) be a polynomial satisfying f(x) : f(1/x) = f(x) + f(1/x) for all XinR :- {O} and f(5) =126, then find f(3).

If f'(x)=(1)/(x)+x^(2) and f(1)=(4)/(3) then find the value of f(x)

If f(x)=(x-1)/(x+1), then find f{f(x)}

If f'(x)=(1)/(x)+(1)/(x^(2)+1) and f(1)=(pi)/(4), find f(x)

If f'(x)=x-(1)/(x) and f(1)=(1)/(2), Find f(x)

If f'(x)=x^2+5 and f(0)=-1 then f(x)=
