Original Khojo Papers practice question — not from a past board paper.
Answer
x2 = 12y
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The vertex is the midpoint of the perpendicular from the focus to the directrix, at the origin, and a = 3, so the equation is x2 = 4ay = 12y.
