From: Shavaun M To: Teacher2Teacher Public Discussion Date: 2010090316:24:48 Subject: Phantom Parabola You have the right idea. But the graphical representation of the phantom parabola is better represented in a third dimension where it cuts the x plane instead of the x axis. The distance B is still represented however when the 'unsolvable' parabola is solved using the imaginary number i, the imaginary soluton is also graphically represented. The phantom parabola simply needs to be hypothetically rotated 90 degrees around a central axis parallel to the y axis.
