I need your help to understand the below question.
I have the polynomial $p(x)=x^3-3x^2-5x-9$ with initial condition $x_0=4$. Asking to compute the first iterates with Newton's method, what is the limit?
I can find the iterates, I also see that Newton's method failed, but I don't get it when ask "what is the limit"?
Anyone has any experience? Thank you all.
