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:
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! 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.
