Consider the following four relations between x and y:
(i) For each relation, state whether its graph represents y as a function of x. Give a brief justification in each case.
(ii) For every relation that IS a function, state its domain and its range.
(iii) Sketch the graphs of all the relations that are functions on one set of axes, clearly indicating intercepts and any end-points.
