Take into account the level curves for the function z =f(x,y) as seen in this graph: %3D 2- -6 -4 2 -9 -8 -7 -6 -5 -6 -7 -8 A. Your friend Jah says, "This isn't a function because if I draw a vertical line, it will intersect with multiple lines." Determine if Jah is wrong or not, and explain your reasoning shortly. В. Find the sign of fy at the point P and briefly explain.
