Please need help only on question 2 iii math analysis question IMG_8007</h1

2. i. Carefully, graph the function f(x, y)=-3x-3y+2 on the first octant of a properly labeled coordinate system.
ii. Use a ruler to generate a contour map for the function f(x, y) = Vx – y , using z=0, 1, and 2 .
iii. Given f(x,y)=-
3-2x’y log, (2xquot;
4xy3 -2x? y
find f,(x, y) . (Do not simplify.)
3-2x’ y 10g, ( 2×3)
iv. Give a point (x, y) where the function f(x, y )=-
cannot be evaluated, and state the reason.
4xy3 – 2x’ y
