\[\left\{ \begin{matrix} y = \sqrt{x} \\ y = \frac{x}{2}\text{\ \ \ } \\ \end{matrix} \right.\ \]
\[\left( \sqrt{x} \right)^{2} = \left( \frac{x}{2} \right)^{2}\]
\[x = \frac{x^{2}}{4}\ \ \ \ \ \ \ | \cdot 4\]
\[4x = x²\]
\[x^{2} - 4x = 0\]
\[x(x - 4) = 0\]
\[x = 0;\ \ \ \ \ x = 4\]
\[y(0) = \frac{0}{2} = 0\]
\[y(4) = \frac{4}{2} = 2\]
\[Ответ:(0;0);\ \ (4;2).\]
