Suppose we wish to use the Method of Lagrange Multipliers to minimize a differentiable function f(x,y) subject to the constraint g(x, y) = 0 which is a closed curve with g E C1. Suppose as well that Vg(a, b) + 0 at all points along the curve g(x, y) = 0. If the global minimum value occurs at (a, b), then which of the following statements are true? Select all true statements. O f. (a, b) = fy(a, b) = 0. At (a, b), Vg(a, b) is parallel to the level curve of f passing through (a, b). O Vf(a, b) = XVg(a, b) for some ) e R. O None of the above

Please do the question on your own and ignore the option i select. Thank you. (even it might be correct)

Suppose we wish to use the Method of Lagrange Multipliers to minimize a differentiable function f(x,y) subject to the constraint g(x, y) = 0 which is a
closed curve with g E C'. Suppose as well that Vg(a,b) # 0 at all points along the curve g(x, y) = 0. If the global minimum value occurs at (a, b), then
which of the following statements are true? Select all true statements.
O f.(a, b) = f,(a, b) = 0.
At (a, b), Vg(a, b) is parallel to the level
curve of f passing through (a, b).
O Vf(a, b) = XVg(a, b) for some X E R.
O None of the above
