Question

This graph is

• A. Relation not a Function
• B. Function not a Relation
• C. Both Relation and a Function
• D. Neither Function nor Relation

Answer 1

The correct option is C Both Relation and a Function


Vertical line test:
For a relation to be a function, a vertical line must cross its graph at atmost one point.
Here, the vertical line cuts the graph at one point. It passes the Vertical line test.
$\therefore$ it is a function.
Every function is a relation. Hence, it is a relation as well.
