A car's fuel efficiency is measured by the distance it can drive per a single unit of fuel. A common unit for efficiency is \text{km/l}km/lstart text, k, m, slash, l, end text, kilometers per liter of fuel. C(S)C(S)C, left parenthesis, S, right parenthesis models the fuel efficiency of a certain car as a function of the car's speed SSS (in kilometers per hour). Match each statement with the feature of the graph that most closely corresponds to it.
