[sage-support] Find real root

Dear all, I have one polynomial f_x(y) =y^3 +f_1(x) y^2 +f_2(x) y + f_3(x). Since it is a cubic polynomial, it has atleast one real root. I want to find that real root as a function of x. I know that x \in [a,b]. -- You received this message because you are subscribed to the Google Groups "sa
