2. For each expression f(x, y) below, D denotes the (natural/largest possible) do- main corresponding to f(x, y). In each case: (i) say whether or not each of the given points belongs to D and justify your answer briefly; (ii) write down an expression for D using set notation; (iii) and draw a sketch of D. (b) f(x, y) = √4x - 2y. (1, 1), (1, -3), (1,3).
