If the domain of the function f(x)=x^(2)-6x+7 is (-oo,oo), then the range of the function is

What is the range of the function f(x)=x^(2)+3x-5 in the domain x in[0,oo)?

If the range of the function F(x)=tan^(-1)(3x^(2)+bx+c) is [0,(pi)/(2)) (domain in R) then :

The range of function f(x)=sqrt(x^(2)+4x)C_(2x^(2)+3) is

The function f(x)=x^(3)+ax^(2)+bx+c,a^(2)le3b has

The range of the function f(x)=|x-1| is A. (-oo,0) B. [0,oo) C. (0,oo) D. R

If expression x^2-4cx+b^2gt0 for all x epsilon R and a^2+c^2ltab then range of the function (x+a)/(x^2+bx+c^2) is (A) (0,oo) (B) (0,oo) (C) (-oo,oo) (D) none of these

If the garph of the function f(x)=ax^(3)+x^(2)+bx+c is symmetric about the line x = 2, then the value of a+b is equal to
