Homework Help: Algebra

Posted by Verti on Tuesday, November 25, 2008 at 5:06pm.

How do you find the standard equation for a parobala when you do not have the directrix? I do have the focus, but the thing is the focus is not a 0,p value, it is -2,5, so I don't see how it could really be a focus. I'm sorry I can't get the graph in this message, but an explanation on finding the standard equation in general will do. Thanks!!!
