Question

This table shows a relation that is a function.Which of the following ordered pairs could be included in the table and have the relationremain a function? Select all that apply.

Answer 1

It is important to know that a function is a relation which associates one element of its domain with a unique element of its range.

Having said that, we can deduct that (2,4) and (-2,7) can be included and the relation will still be a function.

Hence, the answers are (2,4) and (-2,7).
