Hey there!
The domain of a graph is the amount the graph extends on the x axis. In this graph, all the points appear to range from 1 to 6 (both included) on the x axis.
Therefore, your domain would be [1,6] in interval notation form which shows the all the range of values on the x axis.
**note, [ means the value is included, while ( means the value is not included on the graph.
Now, to find the range, or the amount your graph extends on the y axis, you must look at the y values of all your points. When you do, notice that they all range from the values -1, the lowest, and 6, the highest. Because these values are all included, your range would be [-1,6].
Hope this helps!
