Answer:
- domain: (-4, 1]
- range: [0, 9]
Explanation:
You want the domain and range of the given graphed function.
Domain
The domain is the horizontal extent of the graph. The left end is the point (-4, 4), but that point is not included in the domain, as indicated by the open circle. The right end is the point (1, 9). The domain is (-4, 1].
Range
The range is the vertical extent of the graph. The bottom extreme is at y=0, and the upper extreme is the point (1, 9). The range is [0, 9].

Additional comment
Interval notation uses round brackets to indicate a point is not included in the interval, and square brackets to indicate the point is included.
