which of the following represents y = -csc x?

Explanation:

Step1: Recall the properties of $y = \csc x$

The cosecant function $y=\csc x=\frac{1}{\sin x}$. It has vertical - asymptotes at $x = k\pi$, where $k\in\mathbb{Z}$, and its range is $(-\infty,- 1]\cup[1,\infty)$.

Step2: Analyze the effect of the negative sign

The negative sign in $y =-\csc x$ reflects the graph of $y = \csc x$ about the $x$-axis. When $\sin x$ is positive, $\csc x$ is positive and $-\csc x$ is negative. When $\sin x$ is negative, $\csc x$ is negative and $-\csc x$ is positive.

Answer:

The graph that is the reflection of the graph of $y = \csc x$ about the $x$-axis. Without specific labels for the graphs, we can't point out a particular one by name, but it will have the general shape of a cosecant - type graph (U - shaped curves separated by vertical asymptotes at $x=k\pi,k\in\mathbb{Z}$) and be upside - down compared to the standard $y = \csc x$ graph.
