(b) The image below shows the contours in the ry-plane of a smooth surface defined by z f(z,y). Each markedpoint lies on a contour of integer height.D.:- 2:= 1For each of the points A, B, C and D, give all the information you can deduce from the diagram about the first andsecond derivatives of the function f(r,y).

Given the contour, we need to determine about the 1st and 2nd order partials.
