Use the vertical line test to determine whether the relation is a function.
To find: whether the given relation is function or not.
Answer to Problem 6P
The given relation is a function.
Explanation of Solution
Given information:
The graph of given relation is as follows
Concept used:
Vertical line test: The vertical line any where drawn on to the graph of the relation, that
intersect the Exactly at only once with the graph, then the relation is function. Otherwise not.
Calculation:
Apply vertical line test:
From the above vertical line test,
The vertical lines intersect Exactly at once with the graph.
Hence, the given relation is a function.
