comment Finding the dual cone
Thank you for your response however given the simplicity of my question, it's clear I'm a novice. Your response is very textbook-esque, which unfortunately is still somewhat unclear to me. Can you walk through your answer in layman's terms so I might have a chance to understand?

comment Determining if a function is convex
So given $e^{g(x)}$ is convex if $g$ is convex, does it mean that anywhere that $-a \sqrt x $ is not convex then $e^{-a \sqrt x}$ is not convex?

comment Determining if a function is convex
So within the ranges provided for $a$, any value of $\bigtriangledown^2 f(x) $ at the $a$ must be $\succeq 0$ to be convex, correct? In this case $-1 \le a \le 1$ produces negative values so is not convex at those values of $a$...

I see. $f=e^{3x}$ so $\frac{d}{dx}(e^{3x})=3e^{3x}$ which is $3f$.

There are probably things missing which is probably aiding in my confusion. What I was missing is that $du=(1-b)da; \frac{1}{1-b}du=da$ Thank you.
