Объяснение:

Для начала придётся восстановить всю таблицу истинности этой функции (см таблицу 1)

В ней ИСТИНА соответствует логической единице, ЛОЖЬ - логическому нулю. Правее столбца с результатами - промежуточные вычисления.

В итоге видим, что всего три строчки в полученной таблице имеют логический ноль в результате, как и в условии задачи.

Остаётся среди этих трёх строк найти те, что в условии задачи.

В предпоследней строке условия всего одна логическая единица, это строка соответствует отмеченной зеленой в результирующей таблице, и там где логическая единица - столбец x.

В последней строке условия тоже x - равен 1, а это соответствует строке, отмеченной оранжевым, и по истинному значению получаем столбец y. Остаётся последнее соответствие из которой получаем столбцы z и методом исключения w.
