1. The problem statement, all variables and given/known data A maple tree has branch buds. These grow in groups of 3 at the ends of the branches and in groups of 2 at each year's growth of those branches. The largest branch bud in the groups of 3 just extends the existing branch. Describe this with a function and is the function exponential? 2. Relevant equations 2*y years = number of branches from an existing branch 3. The attempt at a solution Year 1: 0 Year 2: 2 Year 3: 8 Year 4: 22 It looks like it is exponential. But is it really or is it a polynomial function?
