Let f(x)-=(x^(2) +bx+c)/(x^(2)+b_(1)+c_(1)) where alpha,beta are the roots of the equation x^(2)+bx+c=0andalpha_(1),beta are the roots of x^(2)+b_(1)x+c_(1)=0 Now answer the following questions for f(x) A combination of graphical and analytical approach may be helpful in solving these problems If alpha_(1)andbeta_(1) are real then f(x)has vertical asymptote at x=alpha_(1),beta_(1).If the equations x^(2)+bx+c=0andx^(2)+b_(1)x+c_(1)=0 do not have real roots then

Answer»

F(x) = 0 has REAL and DISTINCT roots
f(x) = 0 has real equal roots
f(x)=0 has imaginary roots
NOTHING can be said
