The Answer of The fuel efficiency (in miles per gallon) of a sport utility vehicle (SUV) depends on its weight according to the formula  
 $E = 0.00005 x ^ { 2 } - 0.3 x + 41$  
Where x is the weight of an SUV in pounds. According to the model, what is the weight of the least fuel-efficient SUV 
 
A)3,000 pounds
B) 3,100 pounds
C) 2,000 pounds
D) 6,000 pounds
E) 491 pounds

The Fuel Efficiency (In Miles Per Gallon) of a Sport E=0.00005x2−0.3x+41E = 0.00005 x ^ { 2 } - 0.3 x + 41E=0.00005x2−0.3x+41
