### Problem

The number of branches of an oak tree and a birch tree since 1950 are represented by the following tables:
Oak tree
Time (years)Branches
034
346
659
970
1282
Birch tree
Time (years)Branches
08
1033
20128
30512
402049
Determine whether the data described in the tables is best modeled by a linear function or an exponential function.
