Set builder notation is very useful for defining domains.

Find the domain and range of each graph using interval notation worksheet.

Another way to identify the domain and range of functions is by using graphs. 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 x axis the range is the set of possible output values which are shown on the y axis keep in mind that if the graph continues beyond the portion of the graph we can see the domain and. Notice that this graph has one endpoint at 0 0 and an arrow therefore this graph covers all y values that are greater than or. What is its domain.

F of negative 2 is negative 4. 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.
