A maple tree has 3 branch buds at the end of each branch and 2 at each years growth of that branch. At the end of the branch 1 bud lengthens the branch and the other 2 make there be more branches. Describe this with a function and is the growth exponential?
Each and every year the branch grows there is at the end of the branch 3 branch buds. There are also 2 branch buds at the places where growth stopped in the previous years. That is what I mean by "each years growth of that branch"
