Answer:
domain: (–∞,∞) or all real numbers
range: (–∞,∞) or all real numbers
Explanation:
domain is left to right (x-axis). looking at the graph, as you go from left to right, the x-values are infinitely getting more negative and positive.
range is bottom to top (y-axis). as you go from bottom to top, the y-values are infinitely getting more negative and positive.
