Промежутки убывания функции находятся на участках графика, где он направлен вниз.</p><p>В условии задачи указано, что необходимо использовать рисунок из задания 5, который отсутствует. Однако, мы можем проанализировать предложенные варианты ответа и сделать логичное предположение о виде графика. В вариантах ответов в качестве границ промежутков используются точки $a$, $b$ и $c$, которые, вероятнее всего, являются абсциссами точек экстремумов функции.</p><p>Рассмотрим наиболее типичный для подобных задач случай, который описывается вариантом ответа B). Этот вариант предполагает, что у функции есть два промежутка убывания: $(-\infty; a]$ и $[b; +\infty)$.</p><p>Такая ситуация возникает, если на графике функции есть два экстремума:<ul><li>В точке с абсциссой $x=a$ находится точка локального минимума. Это означает, что до этой точки (на промежутке $(-\infty; a]$) функция убывала.</li><li>В точке с абсциссой $x=b$ находится точка локального максимума. Это означает, что после этой точки (на промежутке $[b; +\infty)$) функция также убывает.</li></ul>Между точкой минимума $x=a$ и точкой максимума $x=b$, то есть на промежутке $[a; b]$, функция будет возрастать.Таким образом, график функции, для которой промежутками убывания являются $(-\infty; a]$ и $[b; +\infty)$, сначала спускается до локального минимума в точке $x=a$, затем поднимается до локального максимума в точке $x=b$, и после этого снова спускается. Это стандартный вид для функции, имеющей два экстремума в указанных точках.</p><p>На основании этого анализа, наиболее вероятным ответом является вариант B.</p><p><strong>Ответ:</strong> B) $(-\infty; a]$ и $[b; +\infty)$.</p>" ] #changes: [] #casts: [] #classCastCache: [] #attributeCastCache: [] #dateFormat: null #appends: [] #dispatchesEvents: [] #observables: [] #relations: [] #touches: []

Решение 2. №6 (с. 29)
Для нахождения промежутков убывания функции по её графику необходимо определить, на каких интервалах оси абсцисс (оси $Ox$) график "идёт вниз" при движении слева направо. Функция называется убывающей на некотором промежутке, если для любых двух точек $x_1$ и $x_2$ из этого промежутка, таких что $x_1 < x_2$, выполняется неравенство $f(x_1) > f(x_2)$. Точки, в которых функция меняет характер монотонности (с возрастания на убывание или наоборот), называются точками экстремума. Точки, где возрастание сменяется убыванием, являются точками локального максимума (пиками), а точки, где убывание сменяется возрастанием, — точками локального минимума (впадинами). Промежутки убывания функции находятся на участках графика, где он направлен вниз.
В условии задачи указано, что необходимо использовать рисунок из задания 5, который отсутствует. Однако, мы можем проанализировать предложенные варианты ответа и сделать логичное предположение о виде графика. В вариантах ответов в качестве границ промежутков используются точки $a$, $b$ и $c$, которые, вероятнее всего, являются абсциссами точек экстремумов функции.
Рассмотрим наиболее типичный для подобных задач случай, который описывается вариантом ответа B). Этот вариант предполагает, что у функции есть два промежутка убывания: $(-\infty; a]$ и $[b; +\infty)$.
Такая ситуация возникает, если на графике функции есть два экстремума:
- В точке с абсциссой $x=a$ находится точка локального минимума. Это означает, что до этой точки (на промежутке $(-\infty; a]$) функция убывала.
- В точке с абсциссой $x=b$ находится точка локального максимума. Это означает, что после этой точки (на промежутке $[b; +\infty)$) функция также убывает.
На основании этого анализа, наиболее вероятным ответом является вариант B.
Ответ: B) $(-\infty; a]$ и $[b; +\infty)$.
