If {{MATH_1}} has a local max at {{MATH_2}}, then its square {{MATH_3}} must also have a local max at {{MATH_4}}. {{CMD_5}} Think of {{MATH_6}}. The graph of {{MATH_7}} is a parabola. {{MATH_8}} has a local max at {{MATH_9}}, but {{MATH_10}}, where {{MATH_11}}, has a local minimum at {{MATH_12}}. {{CMD_13}} {{CMD_14}} {{CMD_15}}True{{CMD_16}} {{CMD_17}}False{{CMD_18}} {{CMD_19}}
