Given:
The given equation is
To find:
The vertex, focus, and directrix.
Solution:
The equation of a parabola is
...(i)
where, (h,k) is vertex, and directrix is
We have,
It can be written as
...(ii)
On comparing (i) and (ii), we get
Vertex of the parabola is (2,3).
Therefore, the focus of the parabola is .
Directrix of the parabola is
Therefore, the directrix of the parabola is .
