Motorists often complain about rising gas prices. Some motorists purchase fuel efficient vehicles and participate in trip reduction plans, such as carpooling and using alternative transportation. Other drivers try to drive only when necessary.
Suppose you are at the gas station filling your tank with gas. The function C(g) represents the cost C of filling up the gas tank with g gallons. Given the equation:C(g)= 3.03(g).
For the average motorist, name one value for g that would be inappropriate for this functionâ€™s purpose. Explain why you chose the number you did.
If you were to graph C(g), what would be an appropriate domain? Range? Explain your reasoning.

Would you fit a billion gallons of gas in your tank? Could you afford to?
Would you stop to buy 1 thousandth of a gallon?
The appropriate domain will be somewhere inbetween. You figure out what, based on your own good sense.
Given your domain, the range easily falls into place.
