Creating Models for Quadratic Relationships 1. The number of miles a car can travel on a gallon of gasoline is related to its fuel efficiency. Fuel efficiency depends on many factors including the speed of the car. Driving at very slow or very fast speeds uses more gas than driving at a moderate speed, which means fuel efficiency can often be modeled by a quadratic function. For a certain model of car the fuel efficiency is maximized at 32 miles per gallon with a speed of 55 mph. At 65 mph the car can get 31 miles per gallon. 1. Which form of the quadratic function would be appropriate for modeling the fuel efficiency of this car? Justify your reasoning. es To ovob ras2 oups on yd Debom ed n s i o Relate the information in the problem to the parts of the quadratic equation you selected in part a.
