\[y = \left\{ \begin{matrix} x^{2},\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ если\ x \leq - 2 \\ x + 6,\ \ если\ \ \ x > - 2 \\ \end{matrix} \right.\ .\]
\[f( - 5);\ \ f( - 2);\ \ f( - 1).\]
\[f( - 5) \Longrightarrow ( - 5)^{2} = 25;\]
\[f( - 2) \Longrightarrow ( - 2)^{2} = 4;\]
\[f( - 1) \Longrightarrow - 1 + 6 = 5.\]
