(0.5,-1) is not a critical point for this function.

Wait, how is (0,0) a max? That seems off!

Definitely a saddle point at (0,1).

I think (0,0) is a minimum, not a maximum.

The function has a maximum at (0,0).

I’m pretty sure (0,0) is a critical point, but I can’t recall if it’s a maximum or minimum. I guess I’ll have to double-check my notes!

I think the second derivative test might help here, but I’m a bit confused about how to apply it to this function.

I feel like I’ve seen a similar question where we had to determine the nature of the critical points. I’m leaning towards option C, but I’m not entirely sure.

I remember we practiced finding critical points by taking partial derivatives. I think I need to check if (0,0) is a maximum or minimum.

This seems like a tricky question. I'll need to think carefully about the Dispatcher and Performer model and how exceptions are handled in that context.

Hmm, this looks like a tricky one. I'll need to think through the different levels of the architecture landscape to determine the best answer.

I'm not entirely sure about this one. There are a lot of options, and I'm not familiar with all the details of Field Service configuration. I'll make my best guess, but I might need to come back to this one if I'm unsure.
