• The graph has no symmetry.

Charles and Amy are part of the Environmental Club at school. Their service project for the semester is to get a tree for their school donated and plant it on the school grounds.

Charles’ uncle owns a tree nursery and is willing to donate a 3 foot tall tree that he says will grow 1.5 feet per year.

Amy goes to another nursery in town, but is only able to get tree seeds donated. According to the seed package, the tree will grow 1.75 feet per year.

Charles plants his tree and Amy plants a seed on the same day.

When will the trees be the same size and how tall will they be?

• The trees will be 21 feet tall after 12 years.

• The trees will never be the same height.

• The trees will be 12 feet tall after 21 years.
