Question 436937
No equation provided but since the cost is usually linear it would be represented by C(g) = 3.03g, where 3.03 is the cost per gallon.


b) C(2) = 3.03(2) = 6.06


c) Likewise, C(9) = 3.03(9) = 27.27


d) What is the purpose of finding C(-1)?


e) The domain (and range) are assumed to be the set of nonnegative real numbers (since you can definitely buy zero gallons of gas).
