The function is 
, where 
represents the number of years since from 
.
(a). Graph of the function 
.
In this case 
represents the number of years since from 
, so graph of the function is valid only positive values of .
(b). Estimate the number of alternative-fueled vehicles in use in the United States in 
.
The year represents 
.
Estimate graphically:
The number of alternative-fueled vehicles were there in the United States in the year is 
.
Confirm algebraically:
Substitute 
in .
.
The number of alternative-fueled vehicles were there in the United States in the year is 
.
(c). Observe the graph:
End behavior of the graph : 
.
It appears that as the number of years after increases without bound, the number of alternative-fueled vehicles increases without bound. Due to money and space constraints, infinitely many alternative-fueled vehicles cannot exist.
Therefore, the model is not valid for all years after 
.
(a). Graph of the function is,
(b). vehicles.
(c). It appears that as the number of years after increases without bound, the number of alternative-fueled vehicles increases without bound. Due to money and space constraints, infinitely many alternative-fueled vehicles cannot exist.
Therefore, the model is not valid for all years after .
