23.6.2 Extreme Values on a Limited Interval

Core idea

If x can only run over part of the line, check whether the axis falls inside that interval before deciding between the endpoints and the vertex.

Module goal. Use the vertex to find the maximum or minimum, and translate everyday optimization problems into a quadratic model.
