Question summary: Match each equation with its corresponding extremum {x^3+3·x·y^2-15·x-12·y at the point (2,1); 4·sin(x·y/2) at the origin; x^3+3·x·y^2-15·x-12·y at the point (1,2); x^3+3·x·y^2-15·x-12·y at the point (-2,-1); 8·x^2+16·x-8·y^2-16·y-16 at the point (1,-1)} -> {Absolute maximum; Absolute minimum; Saddle point}
Right answer summary: x^3+3·x·y^2-15·x-12·y at the point (2,1) -> Absolute minimum; 4·sin(x·y/2) at the origin -> Saddle point; x^3+3·x·y^2-15·x-12·y at the point (1,2) -> Saddle point; x^3+3·x·y^2-15·x-12·y at the point (-2,-1) -> Absolute maximum; 8·x^2+16·x-8·y^2-16·y-16 at the point (1,-1) -> Absolute maximum
