The solution
The graph of the function
The domain of the function
The points at which the function is not precisely defined:
$$n_{1} = 0$$
$$n_{1} = 0$$
The points of intersection with the X-axis coordinate
Graph of the function intersects the axis N at f = 0
so we need to solve the equation:
$$\frac{1}{n} = 0$$
Solve this equation
Solution is not found,
it's possible that the graph doesn't intersect the axis N
