Find each key feature of the function shown in the graph.

in the xy graph the range of the x axis is negative 8 to 9 by increment of two. the range of the y axis is negative 8 to 8 by increment of two. on the graph there are open circles at the point (-8, 4) and (4.5, 2). there are closed points at (-4,-4) and (9.5, -2). all these points are joined by solid line.

range =

domain =

is the function positive or negative over the interval (–8, –6)?
