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.
