Explanation:

I'll answer on a general terms, since there are no options appended to the question.

Given

`\{(-2,8),(4,6),(10,4)\}`

Required

Which pair makes the relation not a function?

A relation is represented as:

`\{(x_1,y_1)(x_2,y_2)(x_3,y_4)..........(x_1,y_1)\}`

The x values are referred to as the domain while the y values are the range of the relation.

For the relation to be a function , the x values must be distinct and not repeated.

In the given relation, the domain are: -2, 4 and 10

To get a pair that which the relation will not be regarded as a function; either of -2, 4 and 10 mu st not be repeated.

For instance:

`\{(-2,8),(4,6),(10,4),(10,2)\}` is not a function because 10 is repeated
