Answer:
Explanation:
For a function we have the definition that the mapping must ensure that each x has a unique image of y.
Here we are given two distinct points as
(5,-2) and (x,y)
For these two points to be a function we must have both 5 and x should have unique image.
In other words, if x =5, y must equal -2,
and for x other than 5, y can take any value
So possible values are (5,-2) or (any value other than 5, any real value)
