what is the range of a graph

The range of a graph is the set of possible output values, which are shown on the y-axis/03%3A_Functions/3.03%3A_Domain_and_Range). The domain of a graph, on the other hand, is the set of possible input values, which are shown on the x-axis/03%3A_Functions/3.03%3A_Domain_and_Range). If the graph continues beyond the portion of the graph we can see, the domain and range may be greater than the visible values/03%3A_Functions/3.03%3A_Domain_and_Range). Note that the domain and range are always written from smaller to larger values, or from left to right for domain, and from the bottom of the graph to the top of the graph for range/03%3A_Functions/3.03%3A_Domain_and_Range). To find the domain and range of a function from a graph, we can observe the horizontal and vertical extent of the graph and determine the corresponding domain and range values/03%3A_Functions/3.03%3A_Domain_and_Range).
