algebra question 2

Question

Suppose that the dollar value v(t) of a certain car that is t

 years old is given by the following exponential function.

v(t)=29,000(0.88)^t

Find the initial value of the car.

Does the function represent growth or decay?

By what percent does the value of the car change each year?

Answer 1

29,000

decay

88%

Answer 2

so the initial value of the car is the amount they out in the equation which is 29,000$

This function shows decay because of the 0.88, that means each year that passes the car is only worth 88% of the amount from the previous year

This means the car loses 12% value every year so -12% is the change, 12% decay
