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:
Where:
a is the initial amount = 4000
r is the average rate of increase = 3.8% ==> 0.038
Thus, we have:
Therefore, the exponential model that represents this situation is:
