1. 5, 2. 25, 3. 0, 3. 75,. Which recursive formula can be used to determine the total amount of time spent making hats based on the total amount of time spent previously? f(n 1) = f(n) 1. 5 f(n 1) = f(n) 0. 75 f(n 1) = one-halff(n) f(n 1) = three-halvesf(n).

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. david estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x.
