Question 4 Find all points where the function has any relative extrema or saddle points and identify the type of relative extremum. f ( x, y ) = x2+ xy + y2 - 3x+ 2 Relative maximum at (-2, 1) Relative minimum at (2, -1) and saddle point at (0, 0) Relative minimum at (2, -1) Relative maximum at (2, -1) and saddle point at (0, 0) Previous DD
