From the graph the vertex of the parabola is at $\"\"$ ,

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

The point on the graph of the parabola $\"\"$ , $\"\"$ and $\"\"$ .

(Apply vertex form of the parabola equation: $\"\"$ )

Now we can find a value. $\"\"$

(Substitute 6 for h, 1 for k, 7 for x and 10 for y)

$\"\"$

(Subtract 1 from each side)

$\"\"$

(Substitute 9 for a, 6 for h, and 1 for k)

$\"\"$ $\"\"$

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