#### Answer

$y = 3~csc~\pi x$
The asymptotes have the form $x = n$, for any integer $n$.
The period is $2$.
We can see the graph below.

#### Work Step by Step

$y = 3~csc~\pi x$
When $x = -1$, then $y = 3~csc~(-\pi)~~$ (which is undefined)
When $x = -\frac{1}{2}$, then $y = 3~csc~(-\frac{\pi}{2}) = -3$
When $x = 0$, then $y = 3~csc~0$ (which is undefined)
When $x = \frac{1}{2}$, then $y = 3~csc~\frac{\pi}{2} = 3$
When $x = 1$, then $y = 3~csc~\pi~~$ (which is undefined)
The asymptotes have the form $x = n$, for any integer $n$. The period is $2$.
We can see the graph below.
