Observe the graph:

The vertex of the parabola is at $\"\"$ , So $\"\"$ and $\"\"$ .

Since $\"\"$ is a point on the graph, it satisfies the vertex form of the parabola.

Vertex equation form is $\"\"$ .

Find $\"\"$ .

$\"\"$ (Vertex form)

$\"\"$ (Substitute $\"\"$ and $\"\"$ )

$\"\"$ (Simplify)

$\"\"$ (Divide each side by $\"\"$ )

$\"\"$ (Cancel common terms)

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