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‘ ) = โˆ’ 1 28 ๐‘  2 + (3 + ๐‘š)๐‘  + (31 + ๐‘š) , where ๐‘  is the speed in mi/h and M is measured in mi/gal

a. What is the carโ€™s best gas mileage, and at what speed is it attained? Justify your answer?

b. Sketch the quadratic function manually showing all steps.
