Question 256947: I am really not sure where to classify this problem.
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 of the gasoline per gallon.
b) Find C(2)
c) Find C(9)
d) 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.
e) If you were to graph C(g), what would be an appropriate domain? Range? Explain your reasoning.

You can put this solution on YOUR website! a) What does the number 3.03 represent?
The cost of the gasoline per gallon; the value of g.
---
b) Find C(2)
we can't unless we have a formula.
If C(g) = 3.03g, then we have
C(2) = 2*3.03 = $6.06
--
c) Find C(9)
we can't unless we have a formula.
If C(g) = 3.03g, then we have
C(9) = 9*3.03 = $27.27

d) 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.
There are are a couple of ways to go. We could say G not <= 0, or g NOT > 100. The average motorist would not fill up with 0 gallons or more than 100 gallons
--
e) If you were to graph C(g), what would be an appropriate domain? Range? Explain your reasoning.
The domain would be g > 0. Assume to fill up with gas you get more than 0 gallons.
The range would be C(g) > $0 since you are there to buy gas.
