Check for convexity of the following functions. If the function is not convex everywhere, then determine the domain (feasible set S) over which the function is convex. Apply the graphical technique to verify your answer. a. f = 3x_1^2 + 2x_1x_2 + 2x_2^2 + 7 b. f = x_1^2 + 4x_1x_2 + x_2^2 + 3

Show that the following function is convex or strictly convex on the specified convex set: (a) f(x1, x2) = (x1 + 2x2 + 1)^8 - ln(x1 x2)^2 on D = {(x1, x2) ∈ R^2: x1 > x2 > 1}

Establish whether the following functions are concave, convex, strictly concave, strictly convex, or any: a. f(x1, x2) = x1^2 + x2^2 b. f(x1, x2) = -x1^2 - 4x2^2 c. f(x1, x2) = x1 + 3x1x2 + 6x1^2 + x2^2 d. f(x1, x2) = e^x1 + e^x2 - x1 - x2

Let $I$ be an interval and $f: I \rightarrow \mathbb{R}$ be any function. Show that $f$ is convex on $I$ if and only if the slope of the chord joining $\left(x_{1}, f\left(x_{1}\right)\right)$ and $(x, f(x))$ is less than or equal to the slope of the chord joining $(x, f(x))$ and $\left(x_{2}, f\left(x_{2}\right)\right)$ for all $x_{1}<x<x_{2}$ in $I$.
