Suppose we wish to use the Method of Lagrange Multipliers to minimize a differentiable function f(z,y) subject to the constraint g(z,y) = 0 which is a
closed curve with g € C'. Suppose as well that Vg(a, b) +0 at all points along the curve g(z, y) =0. If the global minimum value occurs at (a, b), then
which of the following statements are true? Select all true statements.
At (a, b), the level curve of f passing through
O (a, b) is tangent to the constraint curve
g(z, y) = 0.
O V/(a, b) = AVg(a, b) for some A E R.
