To explain: The reason that the mapping
Explanation of Solution
Given information: It is given that mapping
A mapping from set A to set B is called a one-to-one mapping if every number of B has exactly one pre-image in A .
Now consider
And
As the points are at different locations therefore the length of AB will be greater than the zero.
But as mapping M maps points A and B to the same image point, the length of the line
Therefore, the mapping does not preserve distance.
