Answer:

$3400

Explanation:

The exponential function describing the value can be written as ...

v(t) = (initial value) · (growth factor)^(t/(growth period))

You are given ...

initial value = 36000

growth factor = 1/2

growth period = 5 years

Then the function is ...

v(t) = 36000(1/2)^(t/5) . . . . where t is in years

For t = 17, the value is ...

v(17) = 36000 · (1/2)^(17/5) ≈ 3410.36

17 years after it was purchased, the value is predicted to be about $3400.
