Hyperbolas of this form:



look like this:  ) (

[Note that x comes first in the equation and ")(" looks a little like an x.]

Hyperbolas of this form:



look like this: 

[Note that y comes first in the equation and the top part,  looks a little 
like the top part of a y, if you use your imagination. lol]
