$$f{\left(x \right)} = \frac{1}{\frac{1}{4} \left(\sqrt{x}\right)^{3}}$$
f = 1/((sqrt(x))^3/4)
The graph of the function
The domain of the function
The points at which the function is not precisely defined:
$$x_{1} = 0$$
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:
$$\frac{1}{\frac{1}{4} \left(\sqrt{x}\right)^{3}} = 0$$
Solve this equation
Solution is not found,
it's possible that the graph doesn't intersect the axis X
The points of intersection with the Y axis coordinate
The graph crosses Y axis when x equals 0:
substitute x = 0 to 1/((sqrt(x))^3/4).
$$\frac{1}{\frac{1}{4} \left(\sqrt{0}\right)^{3}}$$
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
$$\frac{d}{d x} f{\left(x \right)} = 0$$
(the derivative equals zero),
and the roots of this equation are the extrema of this function:
$$\frac{d}{d x} f{\left(x \right)} = $$
the first derivative
$$- \frac{3 \frac{4}{x^{\frac{3}{2}}}}{2 x} = 0$$
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
$$\frac{d^{2}}{d x^{2}} f{\left(x \right)} = 0$$
(the second derivative equals zero),
the roots of this equation will be the inflection points for the specified function graph:
$$\frac{d^{2}}{d x^{2}} f{\left(x \right)} = $$
the second derivative
$$\frac{15}{x^{\frac{7}{2}}} = 0$$
Solve this equation
Solutions are not found,
maybe, the function has no inflections
Vertical asymptotes
Have:
$$x_{1} = 0$$
Horizontal asymptotes
Let’s find horizontal asymptotes with help of the limits of this function at x->+oo and x->-oo
$$\lim_{x \to -\infty} \frac{1}{\frac{1}{4} \left(\sqrt{x}\right)^{3}} = 0$$
Let's take the limit
so,
equation of the horizontal asymptote on the left:
$$y = 0$$
$$\lim_{x \to \infty} \frac{1}{\frac{1}{4} \left(\sqrt{x}\right)^{3}} = 0$$
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/((sqrt(x))^3/4), divided by x at x->+oo and x ->-oo
$$\lim_{x \to -\infty}\left(\frac{4 \frac{1}{x^{\frac{3}{2}}}}{x}\right) = 0$$
Let's take the limit
so,
inclined coincides with the horizontal asymptote on the right
$$\lim_{x \to \infty}\left(\frac{4 \frac{1}{x^{\frac{3}{2}}}}{x}\right) = 0$$
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(-x) и f = -f(-x).
So, check:
$$\frac{1}{\frac{1}{4} \left(\sqrt{x}\right)^{3}} = \frac{4}{\left(- x\right)^{\frac{3}{2}}}$$
- No
$$\frac{1}{\frac{1}{4} \left(\sqrt{x}\right)^{3}} = - \frac{4}{\left(- x\right)^{\frac{3}{2}}}$$
- No
so, the function
not is
neither even, nor odd
