How might you explain your answer to someone who has not learned algebra? The range is the set of possible output values, which are shown on the [latex]y[/latex]-axis. For f(x) = x2, the domain in interval notation is: D indicates that you are talking about the domain, and (-∞, ∞), read as negative infinity to positive infinity, is another way of saying that the domain is "all real numbers.". Students will practice finding the domain and range of discrete and continuous functions given ordered pairs, tables, graphs, equations, mappings, and real life problems. It is over an interval. But how do you define the domain and range for functions that are not discrete? Tools are Your Friend. They will also match the graphs to their corresponding domain and range expressed in int . 4. The graph continues infinitely in the positive direction, whereas the domain in question 1 is discrete. Finally, move to graphs in this order — discrete graphs, graphs with endpoints, and then graphs with arrows. Graph: A discrete graph is a series of unconnected points (a scatter plot).
