Confocal Parabola. The parabola y2=4p(x+p) has its focus at the origin and axis along the x-axis. By assigning different values to p, we obtain a family of confocal parabolas. Such families occur in the study of electricity and magnetism. Show that there are exactly two parabolas in the family that pass through a given point?
I dont know where to start. I have a photo of the picture of the confocal parabolas but for some reason it wont upload. But please help me start. I am so confused.
