Question 436937: Can't figure this out. Can someone please help me figure out how to do this.
1. Imagine 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
a. What does the number 3.03 represent?
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 that number.
e. If you were to graph C(g), what would be an appropriate domain and range? Explain your reasoning.
Answer by richard1234(7193)   (Show Source):
You can put this solution on YOUR website! No equation provided but since the cost is usually linear it would be represented by C(g) = 3.03g, where 3.03 is the cost per gallon.
b) C(2) = 3.03(2) = 6.06
c) Likewise, C(9) = 3.03(9) = 27.27
d) What is the purpose of finding C(-1)?
e) The domain (and range) are assumed to be the set of nonnegative real numbers (since you can definitely buy zero gallons of gas).
