ANSWER:

y= 12000*(0.88)x

Explanation:

We have been given that Jason estimates that his car loses 12% o

Since the value of car is decreasing exponentially, so we will use exponential decay function to find the graph that represents the value of the car after x years.

Answer:


y=12,000*(0.88)^x

Explanation:

Please find the attachment.

We have been given that Jason estimates that his car loses 12% of its value every year. The initial value is $12,000.

Since the value of car is decreasing exponentially, so we will use exponential decay function to find the graph that represents the value of the car after x years.

An exponential decay function is in form:
y=a*(1-r)^x, where,

a = Initial value,

r = Decay rate in decimal form.

Let us convert our given rate in decimal form.


12\%=(12)/(100)=0.12

Upon substituting our given values in decay function we will get,


y=12,000*(1-0.12)^x


y=12,000*(0.88)^x

We can see from our graph that as x approaches infinity, y approaches to zero, therefore, our graph will have a horizontal asymptote at y=0.

Therefore, the function
y=12,000*(0.88)^x represents the value of the car after x years.
