what is the vertex, focus, and equation of directrix

The standard form is , where the focus is (,) and the directrix is .
If the parabola is rotated so that its vertex is (,) and its axis of symmetry is parallel to the -axis, it has an equation of , where the focus is (,) and the directrix is
......here you have an equation of rotated parabola in vertex form
so,
, , =>
= >vertex is at (,)
=> focus is at (,) =(,) = (,)
=> equation of directrix is =>=>=>
