newtons method will fail to approximate the solution to $f(x) = 0$ with initial guess $x_0$ when:

$f(x)$ does not have a root.
$f(x)$ is not a polynomial.
$x_0$ is not close to the solution of $f(x) = 0$.
$f(x_0) = 0$.
$f(x)$ is not differentiable at $x_0$.

$f(x)$ does not have a root.

$f(x)$ is not a polynomial.

$x_{0}$ is not close to the solution of $f(x) = 0$.

$f'(x_{0}) = 0$.

$f(x)$ is not differentiable at $x_{0}$.
