1 point each diagram represents the level curves of a function for each function consider the point above on the surface z flxy a if the vectors below are normal to the surface at the point 86061

SOLVED:Use the level curves of the function z=f(x, y) to decide the sign (positive, negative, or zero) of each of the following partial derivatives at the point P Assume the x - and y axes are in the usual positions. (a) fx(P) (b) fy(P) (c) fx x(P) (d) fy y(P) (e) fx y(P) (FIGURE CAN'T COPY)

Level curves are shown for a function f . Determine whether the following partial derivatives are positive or negative at the point P . (a) fx (b) fy (c) fxx (d) fxy (e) fyy | Numerade
