You can put this solution on YOUR website! Another way to identify the and of functions is by using graphs.
Because the refers to the set of possible values, the domain of a graph consists of all the input values shown on the -axis.
The range is the set of possible values, which are shown on the-axis.
Keep in mind that the graph continues beyond the portion of the graph we can see, the and may be than the visible values.
1 example:
We can observe that the graph extends from ( and is included) to the right , so the domain is [, ).
The vertical extent of the graph is all values and below, so the range is( ,].
Note that the and are from to , or from to for , and from the of the graph to the of the graph for .
