If for all real x `(x+a)/(x^2+b x+c^2)` cannot lie between two limits, then:

If for all real x(x+a)/(x^(2)+bx+c^(2)) cannot lie between two limits,then:

If x be real and 0

If x be real , show that the value of (2x^2-2x+4)/(x^2-4x+3) cannot lie between (-7) and 1.

IF a=(x^2-2x+4)/(x^2+2x+4) and equation of lines AB and CD be 3y=x and y=3x respectively, then for all real x, point P(a,a^2) (A) lies in the acute angle between lines AB and CD (B) lies in the obtuse angle between lines AB and CD (C) cannot be in the acute angle between lines AB and CD (D) cannot lie in the obtuse angle between lines AB and CD
