Let's analyze the problem step by step based on the image of the parabola:

1. Does the parabola open upward or downward?
   From the graph, the parabola opens downward because its arms are facing downwards.

2. Find the intercepts:

   • x-intercept(s):
     The x-intercepts occur where the parabola crosses the x-axis. From the graph, it crosses at $x = -2$.

   • y-intercept(s):
     The y-intercept occurs where the parabola crosses the y-axis. From the graph, it crosses at $y = -1$.

3. Find the coordinates of the vertex: The vertex is the highest point of the parabola since it opens downward. From the graph, the vertex is located at the point $(-2, 3)$.

Here is the
