The function C(g) represents the cost C of filling up | |0 |0 | | |the gas tank with g gallons. Given the equation: [pic] | | | | |A |What does the number 3.03 represent? Relate this |3.03 represents price per gallon that you are paying for at the pumps. | |.5 | | |situation to real life. When you go to a gas | | | | | |station to fill your tank with gas, what are the 3| | | | | |key elements? | | | | |B |Find C(2) Restate the function, substitute the |C(2)=3.03(2) c(2)=6.06 | |.5 | | |given input value, simplify the expression, then | | | | | |state the output value. | | | | | |Remember the units. | | | | |C |Find C(9) Restate the function, substitute the |C(9)=3.03(9) c(9)=27.27 | |.5 | | |given input value, simplify the expression, then | | | | | |state the output value. | | | | | |Remember the units. | | | | |D |For the average motorist, name one value for g |C(15)=3.03(15) c(15)=45.45 | |.5 | | |that would be inappropriate for this function’s | | | | | |purpose. Think about what g represents, then what | | | | | |number would be impossible or improbable to | | | | | |represent this element. | | | | |E |If you were to graph C(g), what would be an |? | |1 | | |appropriate domain? Range? State two intervals | | | | | |describing the minimum and maximum...
