The focus of the parabola : .

The vertex of the parabola : .

Since the - coordinate of the focus and vertex is same, the parabola is horizontal.

Standard form of the horizontal parabola is .

Where

Vertex : ,

Focus : ,

Axis of symmetry : ,

Directrix : .

Vertex of the horizontal parabola : .

So, and .

Focus of the vertical parabola : .

.

Since , the parabola opens right.

Axis of symmetry : ,

Directrix : .

Now write the equation for the parabola in standard form using the values of , and .

Standard form of the vertical parabola is .

Substitute the values of , , and in standard form.

Therefore, the standard form of the equation is .

Construct a table values to graph the general shape of the curve.

The equation is .
