Find the vertex:

Observe the graph, the parabola opens downward and the vertex is located at the maximum point of the parabola. It is located at $\"\"$ . $\"\"$

Find axis of symmetry:

Observe the graph, the axis of symmetry is the line that goes through the vertex $\"\"$ and divides the parabola into congruent halves. It is located at $\"\"$ . $\"\"$

Find y-intercept:

Observe the graph, the y - intercept is the point where the graph intersects the y - axis. It is located at $\"\"$ , so the y - intercept is $\"\"$ . $\"\"$

The graph of the vertex is $\"\"$ , the axis of symmetry is $\"\"$ and y-intercept is $\"\"$ .
