The graph of the function
The domain of the function
The points at which the function is not precisely defined:
$$x_{1} = -1$$
$$x_{1} = -1$$
The points of intersection with the X-axis coordinate
Graph of the function intersects the axis X at f = 0
so we need to solve the equation:
$$\frac{1}{\left(x + 1\right)^{3}} = 0$$
Solve this equation
Solution is not found,
it's possible that the graph doesn't intersect the axis X

Even and odd functions
Let's check, whether the function even or odd by using relations f = f(-x) и f = -f(-x).
So, check:
$$\frac{1}{\left(x + 1\right)^{3}} = \frac{1}{\left(1 - x\right)^{3}}$$
- No
$$\frac{1}{\left(x + 1\right)^{3}} = - \frac{1}{\left(1 - x\right)^{3}}$$
- No
so, the function
not is
neither even, nor odd
