SOLUTION: 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)=3.12(G

Question 389679: 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)=3.12(G)
a) What does the number 3.12 represent?
b) Find C(2)
c) Find C(9)
d) If you were to graph C(g), what values would make up an appropriate domain? Range? Explain your reasoning and remember to include ALL appropriate values.

Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
is the cost/gallon of gas
(b)

(c)

(d) The domain would be appropriate values
for , gallons of gas.
You could put gallons in, but you
can't put (-) gallons in.
You can't put in more than the tank holds
So the domain is
where is capacity of tank in gallons
-----------------
The range is all appropriate values of ,
The cost of putting gallons in
since Cost is either or (+)
and
range is
