Question

Please Help!! A new dirt bike valued at $9000 loses 18% of its value each year. Write a function rule that models the value of the dirt bike.

Answer 1

`y=9000(0.82)^(x)`

Explanation:

General exponential growth/decline equation is given as

`y=ab^(x)`

where a is initial value and b is growth/decline rate

Here a=9000 and b=18%=(1-0.18)=0.82
