\[y = \frac{18}{x}:\]
\[значение\ функции,\ \]
\[если\ значение\ аргумента\ \]
\[равно\ - 2;3;0,6.\ \]
\[y = \frac{18}{x} \Longrightarrow x = \frac{18}{y}\]
\[x = - 2 \Longrightarrow y = \frac{18}{- 2} = - 9;\]
\[x = 3 \Longrightarrow y = \frac{18}{3} = 6;\]
\[x = 0,6 \Longrightarrow y = \frac{18}{0,6} = \frac{180}{6} = 30.\]
