Is the following relation a function?
Yes Or No


Answer:
No
Step-by-step explanation:
A relation is a function when each input has only one output.
To check whether the graph is a function or not , we need to do vertical line test.
Draw vertical lines in the graph . when the vertical line touches the graph at two points, then the relation is not a function.
When we draw vertical line on the U shaped graph, the line crosses the graph at two points. So this relation is not a function
