Any exponential function can be written in the form f(t)=ab^{t} [/tex]
Here as t increases f(t) decreases when b is between 0 and 1 . If b>1 f(t) increases The initial amount is given by the value a.
The growth factor is the value b.
The given function is f(x)= [tex] 22,200( 0.92)^{t} [/tex]
Comparing the equation with exponential function initial amount a= 22,200
The value 22,200 represents option
a. The initial value of the truck is $22,200.
