Observe the graph carefully to identify the extent of the x-values covered by the graph. The domain is the set of all possible x-values for which the graph is defined.
Notice that the graph starts at x = -5 and ends at x = 5. Therefore, the domain of the graph is the interval [-5, 5].
Next, identify the range of the graph, which is the set of all possible y-values that the graph can take.
Observe the lowest point on the graph, which is at y = -5, and the highest point, which is at y = 5. Therefore, the range of the graph is the interval [-5, 5].
Write the domain and range using interval notation: Domain: [-5, 5], Range: [-5, 5].
