23.6.1 The Vertex Is the Extreme Value

The bowl's bottom is lowest and its top is highest; opening upward the vertex gives the minimum, opening downward the maximum, and the value is k.

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