\[y = - \frac{48}{x} \Longrightarrow x = - \frac{48}{y}.\]
\[Найдите:\ \]
\[значение\ аргумента,\ \]
\[при\ котором\ значение\ \]
\[функции\ равно\ 12;\ - 36;100.\]
\[y = 12 \Longrightarrow x = - \frac{48}{12} = - 4.\]
\[y = - 36 \Longrightarrow x = \frac{- 48}{- 36} = \frac{4}{3} = 1\frac{1}{3}.\]
\[y = 100 \Longrightarrow x = - \frac{48}{100} = - 0,48.\]
