comment Can a point be a global extremum but not a local extremum?
One sec. Let's say $f(x)=x^2, \forall x \in \mathbb{R}$. Then isn't the interval $(0.9,1]$ still an open subset of $(-\infty,\infty)$ such that 1 is a local maximum?

Each of the answers below is elucidating. Unfortunately, I can only choose one answer, so I chose the fastest response.

comment Implicit Differentiation Proof
Yes, to some extent, since it says that it's just a special case of the chain rule but it doesn't explain further. Is it because when you are differentiating a mapping with respect to x, you can treat y or any other variables as a function of x and then use the chain rule? That would imply implicit differentiation is generalizable to arbitrarily many other variables. Is that true?

Thank you, Zev. That is exactly what I was looking for.
