Question 10 Find the local extrema of (a) f(x, y) = 2x³ + 6xy² — 12xy. (b) f(x, y) = x + y cos(x). For each function above, determine whether the extrema found are max points, min points, or saddle points. Question 11 Find R f(x, y)dA where f(x, y) = y(r³ - 12x)and R = [0, 1] × [−2, 1]. - Verify that the order of integration. doesn't matter. <
