Try to sort these graphs into families.
- How will you choose to define the families?
- Which features of the graphs will you use?
- Are there some graphs which belong to more than one family?
Once you have sorted the graphs into families
- Try to sketch a further example for each family.
- Try to sketch a graph which would not belong to each family.
How else could you have sorted the graphs?
Please note that these graphs are also used in Gradient match.
