Question

The value of a machine depreciates according to the function f(x)=20000(1/2)x squared, where x is the time in years from the ppurchase of the machine. Find its value after 3 years.

Answer 1

x = 3

 

f(3) = 20000(1/2)³

f(3) = 20000(1/2)(1/2)(1/2)

f(3) = 20000(1/8)

f(3) = 2500

 

The value of the machine after three years is $2,500.
