Log On
the vertex, exactly between the focus and directrix, must be at (, ) = (, )
the absolute value of is the distance between the vertex and the focus and the distance between the vertex and the directrix. (The sign on tells me which way the parabola faces.) Since the focus and directrix are units apart, then this distance has to be one unit, so
Since this is a "upward" parabola, then the part gets squared, rather than the part. So the conics form of the equation must be:
