The graph of the scale is consider the each axis scale is $\"\"$ .

Find the vertex.

Observe the graph:

The parabola opens downward and the vertex is located at the maximum point of the parabola.

Maximum point of the parabola is $\"\"$ .

Vertex is $\"\"$ .

$\"\"$

Find axis of symmetry.

The axis of symmetry is the line that goes through the vertex $\"\"$ and divides the parabola into congruent halves.

Axis of symmetry is $\"\"$ .

$\"\"$

Find $\"\"$ -intercept.

The $\"\"$ - intercept is the point where the graph intersects the $\"\"$ - axis.

It is located at $\"\"$ , so the $\"\"$ - intercept is $\"\"$ .

$\"\"$

Vertex is $\"\"$ .

The axis of symmetry is $\"\"$ .

$\"\"$ -intercept is $\"\"$ .
