Answer:
$15 200
Step-by-step explanation:
The investment is worth $3800 now.
In ten years (one decade), it will have doubled to $7600.
In another ten years, two decades from now, it will have doubled again.
[tex]f(x) = 3800(2)^{x}[/tex] is an exponential function.
f(2) = 3800(2)² = 3800 × 4 = $15 200.
The investment will be worth $15 200 in two decades.
