### Critical Points Classification: Analyzing f(x,y)#### Problem StatementFind and classify (local maximum, local minimum, saddle point) all critical points of the function:\[ f(x,y) = x^2 - x^2y + 2y^2 \]Show all supporting work to completely justify your responses.#### Task Outline1. **Find the Partial Derivatives**: Compute the first-order partial derivatives of $ f(x,y) $ with respect to $ x $ and $ y $.2. **Solve for Critical Points**: Set these partial derivatives equal to zero and solve for $ x $ and $ y $.3. **Classify the Critical Points**: Use second-order partial derivatives and the second derivative test to classify each critical point found.Use detailed step-by-step calculations and ensure all solutions are justified logically and mathematically.#### Detailed Solution Steps1. **Compute $ f_x(x,y) = \frac{\partial f}{\partial x} $** \[ f_x(x,y) = \frac{\partial}{\partial x} (x^2 - x^2y + 2y^2) \]2. **Compute $ f_y(x,y) = \frac{\partial f}{\partial y} $** \[ f_y(x,y) = \frac{\partial}{\partial y} (x^2 - x^2y + 2y^2) \]3. **Find Critical Points** \[ f_x(x,y) = 0 \] \[ f_y(x,y) = 0 \]4. **Second Partial Derivatives** \[ f_{xx}(x,y) = \frac{\partial^2 f}{\partial x^2} \] \[ f_{yy}(x,y) = \frac{\partial^2 f}{\partial y^2} \] \[ f_{xy}(x,y) = \frac{\partial^2 f}{\partial x \partial y} \]5. **Second Derivative Test**: \[ D = f_{xx}(a,b)f_{yy}(a,b) - [f_{xy}(a,b)]^2 \] - If $ D > 0 $ and \(
