(chatquestion)...Let f(x) is a quadratic expression with positive integral coefficients such that for every a, BeR, B>a, [f(x)dx > 0. Let g(t) = f"(t)f(t), and g(0) = 12 then %3D (1) 16 such quadratic expressions are possible (2) f(x) = 0 has either no real root or distinct roots %3D (3) minimum value of f(1) is 6 (4) maximum value of f(1) is 11
