<h2>Answer</h2>
f(x) = 190(1.15)x
<h2>Explanation</h2>
To solve this, we are going to use the standard exponential function:
Where
is the final price after 
years
is the initial price
is the rate in decimal form
is the time in years
We know from our problem that the initial price is $190, so 
. Now to convert the rate, 15%, to decimal form, we are going to divide it by 100%, so 
. Let's replace the values:
3.6 × 10³ + 6.1 × 10³
(3.6 + 6.1) × 10³
