№3.1 (с. 24)
Условие. №3.1 (с. 24)
скриншот условия
3.1. Является ли четной функция:
a) $f(x) = -3x^4 + 2.5x^2$;
б) $f(x) = \cos\frac{2x}{3} - 4x^2 + x$;
в) $f(x) = 5\sin^2x + \frac{1}{2} - x$;
г) $f(x) = -2.5x^6 - 5?$;
Решение. №3.1 (с. 24)
Решение 2. №3.1 (с. 24)
Функция $f(x)$ называется четной, если для любого $x$ из ее области определения выполняется равенство $f(-x) = f(x)$. Область определения ($D(f)$) для всех представленных функций — множество всех действительных чисел ($R$), которое является симметричным относительно нуля. Проверим для каждой функции выполнение условия четности.
а) $f(x) = -3x^4 + 2,5x^2$
Найдем значение функции в точке $-x$:
$f(-x) = -3(-x)^4 + 2,5(-x)^2 = -3x^4 + 2,5x^2$.
Так как $f(-x) = f(x)$, функция является четной.
Ответ: да, функция является четной.
б) $f(x) = \cos\frac{2x}{3} - 4x^2 + x$
Найдем значение функции в точке $-x$:
$f(-x) = \cos\frac{2(-x)}{3} - 4(-x)^2 + (-x)$.
Используя свойство четности функции косинус ($\cos(-\alpha) = \cos(\alpha)$) и свойства степеней, получаем:
$f(-x) = \cos\frac{2x}{3} - 4x^2 - x$.
Сравним полученное выражение с исходной функцией: $f(-x) = \cos\frac{2x}{3} - 4x^2 - x \neq f(x)$.
Условие четности не выполняется, следовательно, функция не является четной.
Ответ: нет, функция не является четной.
в) $f(x) = 5\sin^2x + \frac{1}{2} - x$
Найдем значение функции в точке $-x$:
$f(-x) = 5\sin^2(-x) + \frac{1}{2} - (-x)$.
Так как $\sin^2(-x) = (\sin(-x))^2$ и функция синус является нечетной ($\sin(-\alpha) = -\sin(\alpha)$), то $(\sin(-x))^2 = (-\sin(x))^2 = \sin^2(x)$.
Тогда $f(-x) = 5\sin^2x + \frac{1}{2} + x$.
Сравним полученное выражение с исходной функцией: $f(-x) = 5\sin^2x + \frac{1}{2} + x \neq f(x)$.
Условие четности не выполняется, следовательно, функция не является четной.
Ответ: нет, функция не является четной.
г) $f(x) = -2,5x^6 - 5$
Найдем значение функции в точке $-x$:
$f(-x) = -2,5(-x)^6 - 5 = -2,5x^6 - 5$.
Так как $f(-x) = f(x)$, функция является четной.
Ответ: да, функция является четной.
