Most cars get their best gas mileage when traveling at relatively modest speed. The gas mileage M for a certain new car is modeled by the function. ๐(๐ ) = โ 1/ 28 ๐ ^2 + (3 + ๐)๐ + (31 + ๐) , where ๐ is the speed in mi/h and M is measured in mi/gal
a. What is the carโs best gas mileage, and at what speed is it attained? Justify your answer?
b. Sketch the quadratic function manually showing all steps.
