Me out here since i am having issues

The answer is c. From the graph, it's easy to see that this is an inverse function. This graph is perfectly symmetric around the point (0,0), so it must be a function in the form of y=a/x (plug in -x will get -y). Plug in a random point on the graph such as (2,1) or (1,2), we can derive the function to be y=2/x.
