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

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?

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

-16/4.2/(1)

Is that your question or an answer to A.W's question?

Yes, the problem is correct. The equation C(g) = 3.03g represents the cost C of filling the gas tank with g gallons, where 3.03 represents the cost of one gallon of gas.

The answers provided for parts (a) to (e) are also correct. C(2) represents the cost of filling 2 gallons, so substituting g=2 into the equation gives C(2) = 3.03(2) = 6.06. Similarly, substituting g=9 gives C(9) = 3.03(9) = 27.27.

For part (d), the inappropriate value suggested is -1. This is because it is not possible to buy a negative amount of gas, so using -1 as the number of gallons does not make sense in the context of this function.

Regarding part (e), the appropriate domain for the graph of C(g) would be non-negative numbers, as you cannot have a negative number of gallons of gas. The range would also be non-negative numbers, as the cost of filling the tank with gas would always be a positive value or zero. The reasoning behind this is that the number of gallons cannot be negative, and the cost cannot be negative either (assuming a non-negative price per gallon).
