#### Answer

A

#### Work Step by Step

The function is $y=-\cot x$. In the general equation $y=a\cot bx$, when $a\lt0$, the graph is reflected across the x-axis.
In addition, comparing $y=-\cot x$ to $y=a\cot bx$, we find that $b=1$. The value of $b$ can be used to find the location of the two vertical asymptotes:
$bx=0$ and $bx=\pi$
$1x=0$ and $1x=\pi$
$x=0$ and $x=\pi$
Therefore, the location of the asymptotes is the same as that of the graph of $\cot x$.
Therefore, using this information, we can ascertain that the graph of $y=-\cot x$ will be the same as the graph of $y=\cot x$ except that it will be reflected across the x-axis. This means that the correct graph for $y=-\cot x$ is A.
