Use Newton method interpretation - visual asymptote link

Using \(x_{n+1}=x_n-\frac{f(x_n)}{f'(x_n)}\), with \(x_n=3\), \(f(x_n)=-1\), and \(f'(x_n)=3\), enter \(x_{n+1}\).

Worked practice: result and interpretation

Calculate the requested result first, then choose the interpretation that follows from it.
