Math Help!?

So I'm doing math homework and it was all pretty easy until this came up.....I don't really know where to even begin somebody help please








Suppose you are at a 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)





What does the Number 3.03 represent?





Find C(2)





Find C(9)





For the average motorist, name one value for g that would be inappropriate for this function'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.

Math Help!?
3.03 is the price of the fuel per gallon.





C(2) plug 2 into the function:





3.03(2)= $6.06





repeat that for C(9)





any negative value is inappropriate because you would never return gas to the gas station.





with that in mind the range and domain are both (0, positive infinity)
Reply:no idea
Reply:well wouldn't 3.03 be the cost (C)


so C(2) would be 6.06


and C(9) would be 27.27


?


then I don't know what from there...
Reply:tAtS A HARd ONE ii THiNK yu HAVE TO FIND THE C(2) AND THE C(9) THEN ADD THE NUMBER YOU GET..
Reply:I think 3.03 is the price per gallon or C. Given that C is cost per gallon and (g) is the number of gallons you came up with the formula as follows:


C(g) = 3.03(g)


Therefore if we cancel out the (g) in both sides of the equation you will be left with the following:


C = 3.03
Reply:i choose 3 becuase it is irrational.. and it would really work in this sort of problem..
