Unformatted text preview: Appendix E 1. Imagine you are at a 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 a. What does the number 3.03 represent? 3.03is actually the slope of the linear function b. Find C (2). 3.03 x 2 = 6.06 c. Find C (9). 3.33.03 x 9 = 27.27 For the average motorist, name one value for g that would be inappropriate for this functions purpose. Explain why you chose that number. Well from the looks of it there seems to be no alues of g that are inappropriate, but I could be wrong. e. If you were to graph C ( g ), what would be an appropriate domain and range? Explain your reasoning. Domain: all real numbers Range: all real numbers 2. Examine the rise in gasoline prices from 1997 to 2006. The price of regular unleaded gasoline in January 1997 was $1.26, and in January 2006, the price of regular unleaded gasoline was $2.31 (Consumer price index, 2006). Use the coordinates (1997, 1.26) and (2006, 2.31) to find the slope, or rate of change, between the two points. Describe how you coordinates (1997, 1....
