Answer:

Given in order:

22% growth
12% growth
12% decay
20% decay

Step-by-step explanation:

The exponential function is in the form $f(x)=a(1+r)^x$

If r is positive (the number in the bracket is larger than 1), then it is exponential growth and if r is negative (the number in the bracket is less than 1), then it is exponential decay.

Growth or Decay by how much???

The amount that is greater than/less than 1

The first function's number inside the bracket is greater than 1 by 0.22 (22%). So it is "22% growth".
The second function's number inside the bracket is greater than 1 by 0.12 (12%). So it is "12% growth".
The third function's number inside the bracket is less than 1 by 0.12 (12%). So it is "12% decay".
The fourth function's number inside the bracket is less than 1 by 0.2 (20%). So it is "20% decay".
