Suppose f(x, y) = x² −y+4
(a) On your solution sheet, draw contours of the function z=f(x,y) corresponding to
=
2, 4, 6. Clearly label the axes, and the scale along each axis. Indicate clearly
which contour curve is associated with which z value.
(b) Find the gradient vector Vf (1, 1). Draw this gradient vector on the contour
diagram you sketched for part (a).
(c) What is the maximum rate of change of the function at the point (1,1)? Enter your
answer in the blank below. Round your answer to two decimal places.
