1.3. These contour plots describe \(\partial_x f(x, y)\) and \(\partial_y f(x, y)\). Which is which? Why? Hint: the key is in the straight contours. Refer back to the contour plot of f, and think about your strategy from the previous question. [3 points]

Step 1
In that plot, we saw that the contours of f were straight lines, indicating that f is a linear function. Now, let's analyze the given contour plots. One of the contour plots has straight contours, while the other has curved contours. Based on our previous Show more…

Consider the contour plot for f(x, y) shown below. Use the contour plot to determine the sign of each of the following derivatives of f at P. For each, write one sentence explaining your answer. Assume the x and y axes have the same scale. (i) fx(P) (ii) fy(P) (iii) Duf(P) where u = <-2, -1> (iv) Duf(P) where u = <1, 1>

The figure below is the contour plot of a function of two variables f(x, y), for x and y ranging between 0 to 2 (scale: 1 unit = 5 cm; spacing between contour levels: 0.2). a) Use the contour plot to determine whether fx and fy are > 0, = 0, or < 0 at the point (1, 1.5). Same question at the point (1.2, 0.6)?

Match the surfaces (a) - (f) below with the contour diagrams (1) - (6) below those. (a) Surface (a) matches contour (b) Surface (b) matches contour (c) Surface (c) matches contour (d) Surface (d) matches contour (e) Surface (e) matches contour (f) Surface (f) matches contour
