a) To determine if $f_1(x) = x^2 - 10x$ is convex, concave, or neither, we can find its second d

For each of the following functions, determine that they are convex, concave or neither with the method written in the each option. a) f1 (x) = x ^2 – 10x (prove) b) f3 (x) = 3x1 + 2x1^2 + 4x2 + x2^ 2 – 2x1x2 (use xHf(x)x) c) f4 (x) = x1^ 2 + 3x1x2 + 2x2 ^2 (use determinants of Hessian matrix)
