Suppose I have an equation f(x)=0. I'm trying to find the root of this equation using Newton Raphson method. But when I'm trying to plot this function, the function is starting from 0, that is for x=0 or very very close to 0, this function becomes 0.
My question is, if I calculate the minima of this function, can that be considered as root, since the function is monotonically non decreasing starting from 0?
Or is there any other suitable method available?
