Show is a contour plot for a function z = 3 В A (a) Is fy positive, negative, or zero at A? (b) Is fæx positive, negative, or zero at B? Copy the contour plot onto your own paper. (c) The function f has exactly two critical points in the region pictured. Mark these in the contour plot, label them P and Q, and identify whether each is a local minimum, local maximum, or saddle point. (d) Sketch the gradient of f at A in the contour plot.
