Ответ:

нет таких x

Пошаговое объяснение:

Функция на графике:
y = 1 - |x|,

Как получили:
т.к смещение по Oy на 1 => +1
По графику видно, что это функция должна быть связана с модулем.
Вспоминаем самые популярные графики функций с модулем
y = |x|, добавляем 1
y = |x| +1 , практически то что нам нужно, только (Область значений функции - y), y ∈ [1; +∞). А на графики у нас y ∈ [1; -∞)
Значит ставии - |x|
Наша функция:
y = 1 - |x|


Далее решаем уравнение:
3 = 1 - |x|
|x| = -2 (чего не может быть, модуль всегда положителен)
S = ∅
Из чего делаем вывод, что нет таких x
