Fidel has a rare coin worth $550. each decade, the coin’s value decreases by 10% which kind of function best models the relationship between the coins value? is it increasing or decreasing.

It is decreasing and function represent relationship between coins value is

Step-by-step explanation:

Given: Value of Coin = $ 550

           Rate of Decrease of value of coin = 10% per decade

To find: Function that define relationship between coins value.

let n be the number of decade.

then value of coin after n decade is given by function, f(n)

Clearly we are given rate of decrease of coins value.

So. It is Decreasing.

Therefore, It is decreasing and function represent relationship between coins value is
