Answer: A reflection is a function because each point on the pre-image is mapped to exactly one point on the image.

Step-by-step explanation:

  • A reflection is a rigid motion that moves a shape across a line such that the image looks like the mirror image of the pre-image.
  • A relation is said to be a function if each input value corresponds to a unique output value.

A reflection is definitely a function because each point on the pre-image is mapped to exactly one point on the image such that the image looks like the mirror image of the pre-image.
