The equivalent exponential decay function is given as [tex]m(t)=18000(0.81)^t[/tex]
An exponential function is in the form
y = abˣ
where y, x are variables, a is the initial value of y and b is the multiplier.
Let m(t) represent the value of the car after t years, hence the exponential decay is given by:
[tex]m(t) = 18000(0.9)^{2t}\\\\m(t)= 18000(0.9)^{2(t)}\\\\m(t)=18000(0.81)^t[/tex]
The equivalent exponential decay function is given as [tex]m(t)=18000(0.81)^t[/tex]
