In each case, graph the relation.  For each graph determine if you can find a vertical line that intersects the graph in two places.  If you can, then you cannot call the relation a function.  A function must have a unique value for any given input value. It is perfectly ok if two different input values have the same output, but it is not ok if for one given input, the output is &quot;maybe this, maybe that&quot;.
