A new dirt bike valued at $9000 loses 18% of its value each year.
A function in the form, y=abx
a = initial price
b= the growth or decay factor
x= the number of times it’s multiplied
Growth factors are “1 + the % it’s growing”. Think about it keeping it’s full value and then adding on value to the original.
Decay Factors are “1 - % it’s decaying”. Think about it losing value over time.
Part A
What is the initial price of the dirt bike?
What is the decay factor for the dirt bike?
Write a function rule that models the value of the dirt bike.
Part B (2 points)
Use the exponential function you wrote in Part A to find the value of the dirt bike after 4 years. Show all work. Round to the nearest penny.
