To graph:The given relation and identify if the given relation is a function. If it is not a function draw a vertical line that intersect the graph more than once.
Explanation of Solution
Given information:The relation is
Graph:
The relation is
Interpretation:
The relation is
For a relation to be a function
i) All elements of the set A must be associated to elements in set B.
ii) Allelements of the set A must be associated to a unique element in set B.
Since allthe elements of the domain are related toa single element in the range of the relation, the given relation isa function.
Hence the given relation is a function.
