The x-coordinates of all critical points of {{MATH_8}} (from left to right) are {{MATH_9}}, {{MATH_10}}, and {{MATH_11}}. {{CMD_12}} {{CMD_13}} Now, we evaluate the function {{MATH_14}} at the end points and at the critical points. {{MATH_15}} {{MATH_16}} {{MATH_17}} {{MATH_18}} {{MATH_19}} Now we compare these values and answer the question. {{CMD_20}} The global maximum value of {{MATH_21}} on the interval {{MATH_22}} is {{MATH_23}} and it is attained at {{MATH_24}} and at {{MATH_25}} .
