Suppose an investment of $3,800 doubles in value every decade. the function f(x) = 3,800⋅2xgives the value of the investment after x decades. how much is the investment worth after 2 decades?

$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.

is an exponential function.

f(2) = 3800(2)² = 3800 × 4 = $15 200.

The investment will be worth $15 200 in two decades.
