Now that you know what each means, you should know that we indicate domain and range by using different types of brackets..
( ) > NOT INCLUDING > if on the graph has an open circle at the end it means that
at that end there is an NOT INCLUDING bracket ex: [0, 28)
**IMPORANT RULE** > when dealing with infinity it is automatically a NOT INCLUDING bracket.
[ ] > INCLUDING means that the the whole line is included ex: [0,29]
{ } > SPECIFIC POINTS is when there are specific points on the graph and in that case you
must list ALL the numbers and place them inside these brackets. {2,4,6,8}
Okay, well it is time to see if you know how to figure this out! ... What is the domain and range for the following graphs?
Graph #1 

Graph #2 

Graph #3 


An example of Specific points 
Answers:
Graph #1 Domain: [14.5,infinity), Range: [0, infinity)
Graph #2 Domain: [0,15], Range: [100,200]
Graph #3 Domain: [10, 17], Range: [2,10]
Graph #4 Domain: {1,2,3}, Range: {1,2,3}
Graph #5 Domain: (2,20], Range: [0, 5)
