f(y) = 1*--

         y 
$$f{\left(y \right)} = 1 \cdot \frac{1}{y^{3}}$$
f = 1/y^3
The graph of the function
The domain of the function
The points at which the function is not precisely defined:
$$y_{1} = 0$$
The points of intersection with the X-axis coordinate
Graph of the function intersects the axis Y at f = 0
so we need to solve the equation:
$$1 \cdot \frac{1}{y^{3}} = 0$$
Solve this equation
Solution is not found,
it's possible that the graph doesn't intersect the axis Y
The points of intersection with the Y axis coordinate
The graph crosses Y axis when y equals 0:
substitute y = 0 to 1/y^3.
$$1 \cdot \frac{1}{0^{3}}$$
The result:
$$f{\left(0 \right)} = \tilde{\infty}$$
sof doesn't intersect Y
Extrema of the function
In order to find the extrema, we need to solve the equation
$$\frac{d}{d y} f{\left(y \right)} = 0$$
(the derivative equals zero),
and the roots of this equation are the extrema of this function:
$$\frac{d}{d y} f{\left(y \right)} = $$
the first derivative
$$- \frac{3}{y y^{3}} = 0$$
Solve this equation
Solutions are not found,
function may have no extrema
Inflection points
Let's find the inflection points, we'll need to solve the equation for this
$$\frac{d^{2}}{d y^{2}} f{\left(y \right)} = 0$$
(the second derivative equals zero),
the roots of this equation will be the inflection points for the specified function graph:
$$\frac{d^{2}}{d y^{2}} f{\left(y \right)} = $$
the second derivative
$$\frac{12}{y^{5}} = 0$$
Solve this equation
Solutions are not found,
maybe, the function has no inflections
Vertical asymptotes
Have:
$$y_{1} = 0$$
Horizontal asymptotes
Let’s find horizontal asymptotes with help of the limits of this function at y->+oo and y->-oo
$$\lim_{y \to -\infty}\left(1 \cdot \frac{1}{y^{3}}\right) = 0$$
Let's take the limit
so,
equation of the horizontal asymptote on the left:
$$y = 0$$
$$\lim_{y \to \infty}\left(1 \cdot \frac{1}{y^{3}}\right) = 0$$
Let's take the limit
so,
equation of the horizontal asymptote on the right:
$$y = 0$$
Inclined asymptotes
Inclined asymptote can be found by calculating the limit of 1/y^3, divided by y at y->+oo and y ->-oo
$$\lim_{y \to -\infty}\left(\frac{1}{y y^{3}}\right) = 0$$
Let's take the limit
so,
inclined coincides with the horizontal asymptote on the right
$$\lim_{y \to \infty}\left(\frac{1}{y y^{3}}\right) = 0$$
Let's take the limit
so,
inclined coincides with the horizontal asymptote on the left
Even and odd functions
Let's check, whether the function even or odd by using relations f = f(-y) и f = -f(-y).
So, check:
$$1 \cdot \frac{1}{y^{3}} = - \frac{1}{y^{3}}$$
- No
$$1 \cdot \frac{1}{y^{3}} = \frac{1}{y^{3}}$$
- No
so, the function
not is
neither even, nor odd
