Did I do thes right? 1. 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:

a) What does the number 3.03 represent? The cost for one gallon of gas. 3.03(g)

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

c) Find C(9):C(9)= 3.03(9)=27.27

d) 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. That would be any negative number. Because you can not buy a negative number of amount of gas.

e) If you were to graph C(g), what would be an appropriate domain? Range? Explain your reasoning. Domain= Non-negative numbers, Range= Non-Negative Numbers. It does not make sense to buy a negative number of gallons of gas.
