Given the
function f(x) = 10000(0.73)^x
<span>Where y
is The value of a boat, in dollars, </span>
<span>x
years after its purchase </span>
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
<span> </span>
A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2. f(x) is the value of the function.
