I'll just tag voca so she sees this when shes on @Vocaloid
one second, i am trying to figure this out but i do believe it is above my grade level
You just graph the equations. Which ever one matches the one in your question is the correct answer.
You can use Desmos for graphing. I'll show you how to do it then you can o the rest. Okay?
:O cheating

So I typed in option D. I got this graph. http://prntscr.com/gqt4mq As you can see in the graph that it has the dotted lines down however, it doesn't have it face/pointing in the right direction. It also has the intersection point right. Go through the rest of them and tell me which one you think it is?
maybe it's B ?
http://prntscr.com/gqt5ku C So option C's graph is not only a solid line but it's also pointing in the wrong direction so we know that C can't be it either. http://prntscr.com/gqt5x0 B Option B's graph has the dotted lines correct as well as the intersecting point and the direction of the opening. So option B could be your answer. It's still a good Idea to go through all of the answer choices in case you made a mistake. http://prntscr.com/gqt7hh A Option A's graph has the intersecting point and the direction of the opening right however, the lines are solid, not dotted. So in this case B would be your answer. Hope this helped. ^.^
