Consider the problem of minimizing f(x, y) = x 2 + 2y 2 subject to the constraint

Question:

Consider the problem of minimizing

f(x, y) = x2 + 2y2

subject to the constraint g(x, y) = yex2 - 1 = 0.

(A) Solve the constraint equation for y, and then substitute into f(x, y) to obtain a function h(x) of the single variable x. Solve the original minimization problem by minimizing h (round answers to three decimal places).

(B) Confirm your answer by the method of Lagrange multipliers.
