\[- 0,5x^{2} = x - 4\]
\[\left\{ \begin{matrix} y = - 0,5x² \\ y = x - 4\ \ \ \\ \end{matrix} \right.\ \]
\[y = - 0,5x²\]
\[x\] | \[0\] | \[1\] | \[- 1\] | \[2\] | \[- 2\] |
---|---|---|---|---|---|
\[y\] | \[0\] | \[- 0,5\] | \[- 0,5\] | \[- 2\] | \[- 2\] |
\[y = x - 4\]
\[x\] | \[3\] | \[4\] |
---|---|---|
\[y\] | \[- 1\] | \[0\] |
\[Ответ:x_{1} = 2;\ \ \ x_{2} = - 4.\]
