Question

Every mapping is a relation but every relation is not a mapping.

• A. True
• B. False

Answer 1

The correct option is A True

For a function every element belonging to A must have an image and that too unique. In a relation a particular element belonging to A may not have an image at all in B or if it has an image, it need not be unique i.e. it can have so many images. Every mapping is a relation but every relation is not a mapping.
