Question

The value of a boat, in dollars, x years after its purchase is represented by the function.

Answer 1

Given the function f(x) = 10000(0.73)^x

Where y is The value of a boat, in dollars, x years after its purchase 
at x = 1
f(1) = 10000(0.73)^1
f(1) = $7300  
at x = 2
f(2) = 10000(0.73)^2
f(2) = $ 5329  
so the decrease
D = $7300 - $ 5329
D = $ 1971
