Answer:
Given in order:
- 22% growth
- 12% growth
- 12% decay
- 20% decay
Step-by-step explanation:
The exponential function is in the form [tex]f(x)=a(1+r)^x[/tex]
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".
