Where: function F(x, y) of two variables by: F(x, y) = f(g(x, y), h(x, y)) f(s, t) = st² g(x, y) = x + y² h(x, y) = x²y Use the chain rule to calculate F(x, y) and F, (x, y). Are the following functions concave, convex, strictly concave, strictly convex, or neither: z = x² z = x² + 2x² z = 2x² - xy + y
