Question

Does the graph represent a one-to-one function?

• A. Yes
• B. No
• C. Can't be predicted from the graph
• D. Maybe

Answer 1

The correct option is B No

From a vertical line test, a graph to be a function, every vertical line intersects the curve in atmost one point.
In the above graph vertical line intersects at two points. So, it is not a function.
$\therefore$ It cannot be one-one function.
