Josiah claims that the ordered pair (6,-10) can be replaced with any ordered pair and the set will still represent a function. Select all ordered pairs that could be used to show that this claim is incorrect

Complete Question:

{(–9, 1), (–5, 2), (0, 7), (1, 3), (6, –10)} Josiah claims that the ordered pair (6, –10) can be replaced with any ordered pair and the set will still represent a function. Select all ordered pairs that could be used to show that this claim is incorrect.

A. (–10, –10)

B. (–9, –6)

C. (–5, 1)

D. (1, 12)

E. (4, 7)

Step-by-step explanation:

A relation is represented as:

Where

For a relation to be a function, the domain must be unique and must not be repeated.

In the given function,

The domains are

So, if (6,-10) is to be replaced;

The domain of the ordered pair that will replace it must not be any of

From the list of given options:

The above can not replace (6,-10) because their domain exist already.

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
