To describe: the whether the given relation is function or not with the use of vertical line test.
Explanation of Solution
Given information:
The given graph is as follows
Concept used:
Vertical line test:
If the vertical lines drawn along the y-axis on to the given graph are intersecting at only one point, then the relation is a function.
