x²>36, значит числа больше 36, осколько числа от -6 до 6 не вклюая не подходят потому что они <36, то правильныц ответ номер 1 (-∞;-6]n[6;+∞)

Только начинаю работать в Unity, помогите пожалуйста.
Ошибка в Unity:
"MissingReferenceException: The object of type 'GameObject' has been destroyed but you are still trying to access it.
Your script should either check if it is null or you should not destroy the object.
