Answer Key

1)  It is exponential decay function.

2) it is exponential growth function.

3) So, it is neither.

4) So, the function is exponential growth function.

5)  So, the function is neither.

6)  So, the function is exponential decay function.

7)  So, the function is exponential growth function.

8)  So, the function is exponential decay function.

9)  So, the function is exponential growth function.

10)  So, the function is exponential decay function.
