Вопрос:

Ответ:

\[f(x) = - 1,5\ \ \]

\[при\ \ x = - 2,5;\ \ x = - 1,5;\ \ \]

\[x = 3;\ \]

\[f(x) = 1,5\ \ \]

\[при\ \ x = - 0,5;\ \ x = 2;\ \ x = 4,5;\ \]

\[f(x) = 3\ \ \]

\[при\ \ x = 0;\ \ x = 1,5;\ \ x = 5;\ \]

\[f(x) = 0\ \ \]

\[при\ \ x = - 3,5;\ \ x = - 1;\ \ \]

\[x = 2,5;\ \ x = 4.\]
