1. [7 marks] (a) Graph the function f(x) = 1/x (b) Hence, using translations, reflections etc., obtain the graph of f(a) = -2+ - 3 showing all intermediate graphs and indicating the transformations used. 2. [6 marks For each of the following functions, give the domain and range using interval notation, showing your reasoning. (When the domain is not specified, we adopt the convention that the domain consists of all numbers for which the function is defined.) (a) f(x) = V16-12 (b) f(x) = vx2 - 2.x - 3
