Given information: Relation is
Calculation:
Relation is given as follows:
When
When
When
Graph is sketched as follows:
In order to validate that the relation is a function or not, draw any vertical line that intersects the graph more than once.
There do no exists any vertical line that intersects the graph more than once
Thus, the relation is a function.
Conclusion:
Hence, graph of equation is sketched and given relation is function.
