Consider the function f(z, y) = 2r - 4r – ry? + 2y? – 3. %3D (a) Find the first-order and second-order partial derivatives of f(x, y). (b) Use the chain rule for small changes to estimate the change in f that occurs when (r, y) changes from (0, 1) to (0.01,0.99). (c) Show that the stationary points of f(r,y) are at (2,-2), (1,0) and (2,2).
