Consider the level curves for function z = f(x,y) below 3 2- P -9 -8 -7 -6 -5 -6 -7 -8 -9 A. Your buddy states "This isn't a function because if I draw a vertical line, it will intersect with multiple lines." State whether your buddy is correct or incorrect, and briefly explain why. B. Determine the sign of fy at the point P and briefly explain.
