1. (a) Sketch the graph of the function f(x,y) = x2 + (y - 1)2 – 2, and describe this surface. (Note: Your sketch must be drawn by hand and not computer generated. Your description should include sufficient detail for someone to uniquely identify the surface.) (b) Let 3- y +2 9(2,3) +y where x and y are real variables. (1) Find the natural domain D. of g, and compute the corresponding range of 9. Justify your answers. (ii) Sketch (by hand), on a single xy-plane, the level curves of g(x,y) of heights z = -1, 2 = 0, and 2 = 1. Clearly label the three level curves on your sketch
