Question 1118138: The amount of carbon dioxide (in pounds per 15,000 cubic miles) released by a certain SUV depends on its fuel efficiency according to the formula
W = 30x^2 − 1950x + 44,000 (12 ≤ x ≤ 33)
where x is the fuel efficiency of an SUV in miles per gallon. According to the model, what is the fuel efficiency of the SUV with the least carbon dioxide pollution?

You can fit the numbers correspondingly; but for y=ax^2+bx+c, the vertex is for and . You can try to complete the square on the given equation to put into vertex form to see.
