Question

I am offering 750 points for this problem.

The only caveat is that I need fairly detailed explanation of what exactly is going on and what we are looking at.

It is not covered in my text nor can I find helpful sites on the internet.

Again, please explain what is going on here, what are they asking, and how we arrive at the answers.

The more explanation, the better.

(I assume when they say that the values of f on the contours are omitted, they are talking about the z values?

Anyway, if anyone cares to try, here is the problem.

Also, what does fx(P) or fy(Q) mean?

on the contours omitted.

Explanation / Answer

fx = Lt(h->0)(f(x+h)-f(x))/h

Since y-cordinate at P is inc with increase in x-cordinate,

a)fx(P) > 0

b)fx(Q) <=0

c)fy(Q) <=0
