It means which one of these points are on the graph, this is what is the questions asking.

I've plugged in each one, but none of them fit correctly. What am I doing wrong?

anonymous · Answer

@Macks  maybe you did a typo error while plugging in the numbers. Try using an online calculator. Like wolframalpha.

The answer is B. 

By thinking about it if you cube a positive number then times it by a negative one you should get a negative output. You can use this methadology for the process of elimination.
