If (x^(2)+ax+3)/(x^(2)+x+a) , takes all real values for possible real values of x, then

If f(x)= x^(3) + ax^(2) + bx + c is an increasing function for all real values of x then-

Let y^(2) = ((x+5)(x-3))/(x-1) , then all the real values of x, for which y has non-zero real values , are :

If f(x)=x^(2) is a real function, find the value of f(1).

If f(x)=x^(2) is a real function, find the value of f(1).

If ax^(2)+bx+c=0 is satisfied by every real value of x, then
