\[4x^{- 2} = x + 3\]
\[\left\{ \begin{matrix} y = 4x^{- 2}\ \\ y = x + 3 \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ }\left\{ \begin{matrix} y = \frac{4}{x^{2}}\text{\ \ \ \ } \\ y = x + 3 \\ \end{matrix} \right.\ \]
\[y = \frac{4}{x^{2}}\]
\[x\] | \[1\] | \[2\] | \[3\] | \[- 1\] | \[- 2\] | \[- 3\] |
---|---|---|---|---|---|---|
\[y\] | \[4\] | \[1\] | \[\frac{4}{9}\] | \[4\] | \[1\] | \[\frac{4}{9}\] |
\[y = x + 3\]
