Let F(x) be the antiderivative of the polynomial function f(x) whose coefficient of the highest term is 1 and satisfying the following
x≤ft\4x+d/dxF(x) \=-x^3+1/9\f'(x)\^2+xf(0)
for all real numbers x. If lim x→0fracf(x)x^2=3, find f(2).
F(x) — bosh koeffitsiyenti 1 ga teng va barcha haqiqiy x sonlar uchun quyidagini qanoatlantiruvchi f(x) ko‘phadning boshlang‘ich funksiyasi bo‘lsin:
x≤ft\4x+d/dxF(x) \=-x^3+1/9\f'(x)\^2+xf(0)
Agar lim x→0fracf(x)x^2=3 bo‘lsa, f(2) ni toping.
