In 2013 your car was worth $12,500. in 2015 your car was worth $8,200.
a) suppose the value of your car decreased at a constant rate of change. define a function f to determine the value of your car (in dollars) in terms of the number of years t since 2013.
b) suppose the value of your car decreased exponentially. write a function g to determine the value of your car (in dollars) in terms of the number of years t since 2013

A)

B)  

Step-by-step explanation:

In two years i.e. from 2013 to 2015 the car value decreases from $12500 to $8200.

a) If the rate of decrease is constant and it is r% per year, then

⇒ r = 17.2%

Therefore, the value of the car is given by , where, t is in years since 2013. (Answer)

b) If the rate of decrease is exponential and it is r%, then

⇒ r = 19%

Therefore, the value of the car is given by , where, t is in years since 2013. (Answer)

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
