The solution

You have entered [src] 
f(x) = csc(x)
f(x)=csc⁡(x)f{\left(x \right)} = \csc{\left(x \right)} 
f = csc(x)
The graph of the function
02468-8-6-4-2-1010-10001000
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:
csc⁡(x)=0\csc{\left(x \right)} = 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 csc(x).
csc⁡(0)\csc{\left(0 \right)}
The result:
f(0)=∞~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
ddxf(x)=0\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:
ddxf(x)=\frac{d}{d x} f{\left(x \right)} =
the first derivative
−cot⁡(x)csc⁡(x)=0- \cot{\left(x \right)} \csc{\left(x \right)} = 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
d2dx2f(x)=0\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:
d2dx2f(x)=\frac{d^{2}}{d x^{2}} f{\left(x \right)} =
the second derivative
(2cot⁡2(x)+1)csc⁡(x)=0\left(2 \cot^{2}{\left(x \right)} + 1\right) \csc{\left(x \right)} = 0
Solve this equation
Solutions are not found,
maybe, the function has no inflections
Horizontal asymptotes
Let’s find horizontal asymptotes with help of the limits of this function at x->+oo and x->-oo
lim⁡x→−∞csc⁡(x)=⟨−∞,∞⟩\lim_{x \to -\infty} \csc{\left(x \right)} = \left\langle -\infty, \infty\right\rangle
Let's take the limit
so,
equation of the horizontal asymptote on the left:
y=⟨−∞,∞⟩y = \left\langle -\infty, \infty\right\rangle
lim⁡x→∞csc⁡(x)=⟨−∞,∞⟩\lim_{x \to \infty} \csc{\left(x \right)} = \left\langle -\infty, \infty\right\rangle
Let's take the limit
so,
equation of the horizontal asymptote on the right:
y=⟨−∞,∞⟩y = \left\langle -\infty, \infty\right\rangle
Inclined asymptotes
Inclined asymptote can be found by calculating the limit of csc(x), divided by x at x->+oo and x ->-oo
True

Let's take the limit
so,
inclined asymptote equation on the left:
y=xlim⁡x→−∞(csc⁡(x)x)y = x \lim_{x \to -\infty}\left(\frac{\csc{\left(x \right)}}{x}\right)
True

Let's take the limit
so,
inclined asymptote equation on the right:
y=xlim⁡x→∞(csc⁡(x)x)y = x \lim_{x \to \infty}\left(\frac{\csc{\left(x \right)}}{x}\right)
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:
csc⁡(x)=−csc⁡(x)\csc{\left(x \right)} = - \csc{\left(x \right)}
- No
csc⁡(x)=csc⁡(x)\csc{\left(x \right)} = \csc{\left(x \right)}
- Yes
so, the function
is
odd
