To analyze the domain of the downward-opening quadratic function:

1.Graph Shape: From the graph, we can observe that it is a parabola that opens downward. This indicates that it has a maximum point, meaning the function values will rise to this peak and then decline.

2.Vertex: The vertex is located at (-1, 0), which represents the highest point on the graph. The function will yield values less than or equal to 0 for any x less than or greater than -1.

3.Horizontal Extent: The ar...
