The focus of the parabola is
and the parabola contains
.
Parabola is opens up.
\Standard form of the vertical parabola is
.
Where vertex :
, focus :
, axis of symmetry :
and directrix :
.
Focus of the vertical parabola :
.
So,
and
.
.
Vertex of the vertical parabola :
.
Substitute
and
in standard form.

and
.
As the parabola opens up,
.
Therefore,
.
Vertex of parabola :
.
Axis of symmetry :
.
Directrix :
.
Standard form of the vertical parabola is
.
Substitute the values of
,
and
in standard form.

Therefore, the standard form of the equation is
.
Graph :
\Plot the vertex, focus.
\Graph the parabola
, axis of symmetry
and directrix
.

The standard form of the equation is
.
Graph of the
