Domain And Range Of A Relation Graph
We discuss how to identify and write the domain and range of relations from a graph.
Domain and range of a relation graph. Points a 2 3 has the smallest x coordinate. A relation is just a relationship between sets of information. The arrow at the top right of the graph indicates that the graph continues to the left as x increases.
Hence they represent a relation. When x and y values are linked in an equation or inequality they are related. Note example 1 is x gre.
The range is the set of possible output values which are shown on the y axis. Not all relations are functions. Keep in mind that if the graph continues beyond the portion of the graph we can see the domain and range may be greater than the visible values.
A function states that given an x we get one and only one y. Howard on twitter mrhowardmath. Another way to identify the domain and range of functions is by using graphs.
