INFORMATION:
We have the next function

We must rewrite it in the form y = a(1+r)^t or y = a(1-r)^t and state the growth or decay rate
STEP BY STEP EXPLANATION:
To rewrite the function:
1. Write the original function

2. Use exponential properties

3. Simplify

4. Rewrite in form y = a(1-r)^t

Finally, r = 0.14. That means that the rate is 14% and since we used the form y = a(1-r)^t, it is a decay rate.
ANSWER:
1.

2. The rate is 14%
3. This is a decay rate.
