Answer 1

The first one is exponential since it’s compounded interest or compounded annually meaning it increases with the amount previously in it. There is a large increase.
2. It is linear since the 2 quarters will be added each week and they remain constant meaning he doesn’t change the amount if quarters or adds it every other week.
