Hi, guys, I have a questions to ask you about Newton's Method.(adsbygoogle = window.adsbygoogle || []).push({});

I knew that Newton's Method was used to estimate the true value of the root of the real number by analysis the graph of that particular function, but I just wonder that do I have to plot the graph of the function everytime I want to use newton's method, my understanding was 'yes', I think that ploting the graph help me to know "what value" will be used to be x1 or the approximate answer I was looking for, I'm I right or wrong ????

suppose the problem wants me to find x intersect of f(x) = x^7-1000 by using Newton's Method

Do I have to plot this graph first in order to approximate the value of x1

Thank you so much, sir !!!!!
