If f(x) is a differentiable function in the interval (0, ∞) such that f(1) = 1 and limit t→x t^2f(x) - x^2f(t)t - x = 1 , for each x > 0 , then f (32) is equal to:

How to Prove That the Function is Not Differentiable

Show that if f is differentiable on an open interval and f^'(x) ≠0 on the interval, the equation f(x)=0 can have at most one real root in the interval. | Numerade
