Consider the functions: f(x), g(x), w(x) : R4 - R, con f(x) > 0, g(x) > 0, w(2) > 0 h(x) f (x)g(x) ew(x) Suppose further that f(x) and g(x) are concave, and w(x) is convex. Suppose f is homogeneous of degree k = 1/3, g is homogeneous of degree k = 1/4 , and w is homogeneous of degree k = 0. Determine whether the following function h is concave(quasi), convex(quasi) or nothing
