Observe the graph of the parabola. It opens upwards, indicating that the vertex is a minimum point.
Identify the vertex of the parabola by locating the lowest point on the graph. This point is where the parabola changes direction.
From the graph, the vertex appears to be at the point (-3, -2).
Since the parabola opens upwards, the vertex represents a minimum value of the function.
Thus, the ordered pair of the vertex is (-3, -2), and it is a minimum point.
