The range is the set of possible output values, which are shown on the [latex]y[/latex]-axis. 7th - 9th grade . On a graph, you know when a function includes or excludes an endpoint because the endpoint will be open or closed. But how do you define the domain and range for functions that are not discrete? Answer: The domain of this graph is over an interval (continuous) with one defined endpoint. 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.".
