Q27·Section A (Section A)·27 of 60Local minima of a cubic polynomial in two variablesLet f(x,y)=x2−400xy2f(x,y)=x^2-400xy^2f(x,y)=x2−400xy2 for all (x,y)∈R2(x,y)\in\mathbb R^2(x,y)∈R2. Then fff attains its OptionsAlocal minimum at (0,0)(0,0)(0,0) but NOT at (1,1)(1,1)(1,1)Blocal minimum at (1,1)(1,1)(1,1) but NOT at (0,0)(0,0)(0,0)Clocal minimum both at (0,0)(0,0)(0,0) and (1,1)(1,1)(1,1)Dlocal minimum NEITHER at (0,0)(0,0)(0,0) NOR at (1,1)(1,1)(1,1)Pick an option to check your answer.Show answerShow solution Report a problem with this question← Q26All questionsQ28 →Keyboard: A–D answer · S solution · ←/→ previous/next
