Answer

The fraction of your face that you can see remains the same, no matter how far you hold the mirror. You'd need a larger mirror to see more.

Work Step by Step

See the diagram. You will see a part of your face that is twice the size of the mirror, whether you hold it close or at arm’s length. If you move closer to the plane of the mirror, the image of your face moves closer too. Try it and see!
