The vertex of the parabola is $\"\"$ and the directrix $\"\"$ .

The equation of the parabola is in the form of $\"\"$ .

Here $\"\"$ is the vertex of the parabola and the directrix of the parabola is $\"\"$ .

Hence $\"\"$ and $\"\"$ .

Substitute $\"\"$ .

$\"\"$

$\"\"$ .

Since $\"\"$ , the parabola opens up.

$\"\"$

The equation of parabola is $\"\"$ .

Substitute $\"\"$ and $\"\"$ .

$\"\"$

$\"\"$ .

Therefore, the equation of the parabola is $\"\"$ .

$\"\"$

The equation of the parabola is $\"\"$ .
