1. = (a) Sketch the graph of the function f(x, y) = V 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 X – Y + 2 g(x,y) x + y where x and y are real variables. (i) Find the natural domain D of g, and compute the corresponding range of g. Justify your answers. (ii) Sketch (by hand), on a single xy-plane, the level curves of g(x, y) of heights -1, z = = 0, and z = 1. Clearly label the three level curves on your sketch. z =
