Algebra-2

From the graph, it shows a line segment with two solid endpoints: (-5, -9) and (4, 6)

The domain is the set of all x-values for which the function is defined.

The leftmost point of the graph is at (-5, -9), where is a solid point.

The rightmost point of the graph is at (4, 6), where is also a solid point.

Thus, the domain includes all x-values from -5 to 4, inclusive. The domain is: [-5, 4].
