Directrix is equidistant from the focus of the parabola. Is it possible that the directrix can be placed anywhere in the cartesian plane and still make a legitimate parabola ? Or is there a limit for where the directrix to be placed to form a legitimate parabola in a cartesian plane. Thanks in advance
