Question
Find all relative extremes and any saddle points
The function given is: \[ f(x, y) = x^2 y - 2x^2 - y^2 + 4 \] This is a multivariable function involving both \(x\) and \(y\). The expression consists of the following terms: - \(x^2 y\): A term where \(x\) is squared and multiplied by \(y\). - \(-2x^2\): A term where \(x\) is squared and multiplied by \(-2\). - \(-y^2\): A term where \(y\) is squared and multiplied by \(-1\). - \(+4\): A constant term. This function can be used to analyze relationships between two variables, \(x\) and \(y\), and to explore concepts such as partial derivatives and critical points in multivariable calculus.
