Suppose you are at the gas station filling your tank with gas, The function C(g) represents the cost C of filling the tank up the gas tank with g gallons. Give the equation: C(g)=3.03g

Question

a) What does the number 3.03 represent? The cost of one gallon of gas; C(g)=3.03(g).
b)Find C(2); C(2)=3.03(2)C(2)=6.06
c)Find C(9); C(9)=3.03(9); C(9)=27.27
d) For the average motorist, name one value for that would be inappropriate for this function's purpose. Explain why chose the number you did. -1 would be in appropriate for this funtion's purpose. Because, you can not buy a negative number of amount of gas.
e)If you graph C(g), what would be the appropriate domain?Range? Explain your reasoning. Domain= non-negative numbers and Range= non-negative numbers. It does not make sense to buy a negative number amount of gallons of gas.
My question is this problem right?

Answer 1

a) Correct. The price per gallon
b) Correct
c) Correct
d) A good example
e) Domain: 0 to the size of your gas tank, in gallons (N)
f) 0 to 3.03 N

Answer 2

-16/4.2/(1)
