www.math.usm.edufunction de ned on the range of f(x, then the composition g(f(x)) is strictly convex on C. Example Let f(x;y;z) = ex2+y2+z2. This function is strictly convex on R3, as it is a composition of a strictly increasing convex function g(y) = ey with a function h(x;y;z) = x2 +y2 +z2 that has
