Question 182333
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:  C(g)=3.03(g)
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. 
---
Ans: g = -2 because -2 cannot express the cost of a gallon of gasoline.
--------------------------------------------------------------------------

e)If you were to graph C(g), what would be an appropriate domain? Range?
Domain: all Real numbers >= zero
Range: all rational numbers >= zero
---------
Explain your reasoning. 
Range is the cost of the gasoline which involves rational numbers
to two decimal places but does not involve irrational numbers or
imaginary letters.
