Given:

Initial amount = $4000

Rate of increase = 3.8% per year

Let's write the exponential function that represents this situation.

The exponential function will be an exonential growth function since the rate is increasing.

Apply the exponential growth formula:


y=a(1+r)^x

Where:

a is the initial amount = 4000

r is the average rate of increase = 3.8% ==> 0.038

Thus, we have:


y=4000(1+0.038)^x

Therefore, the exponential model that represents this situation is:


y=4000(1+0.038)^x

ANSWER:


y=4000(1+0.038)^x
