Instructions: For each assigned problem show your steps taken to get the final answer (the rows will automatically expand as you enter text). Then, restate your final answer in the Answer column. If the problem includes units of measure, be sure to include the units. Download and name this file as LastnameFirstnameMat116SGE. Post to the Assignments Section. Use a math editor (Equation Editor or MathType) to write all math text to insure proper formatting of work and answers. |# | |Show your Work using a math editor and state Final Answer |- pts |+ pts | |1 |Suppose you are at the gas station filling your tank with gas. 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?

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?
