Respuesta :

Since the maximum capacity of Mark's car is 20 gallons, so he can buy up to 20 gallons or even 20 gallons. Then

[tex]g\le20[/tex]

On the other hand, since it doesn't make sense for Mark to buy 0 gallons then he will buy more than 0 gallons. Then

[tex]0Therefore, the most appropriate domain of the function is [tex]g\le20[/tex]
