Finding Domain And Range Of A Function On A Graph
The range is the set of possible output values which are shown on the y axis.
Finding domain and range of a function on a graph. The range is all the values of the graph from down to up. We observe that the graph corresponds to a continuous set of input values from 2 2 to 3. Thus the domain of the function is 2 3 2 3 also the variation in the function output is in the continuous interval from 1 1 to 4.
Another way to identify the domain and range of functions is by using graphs. When looking at a graph the domain is all the values of the graph from left to right. Find the domain and range of the function.
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. Because the domain refers to the set of possible input values the domain of a graph consists of all the input values shown on the latex x latex axis.
