Chapter 4, Problem 7CA

To determine

To find: The relation of five ordered pairs

Answer to Problem 7CA

The relation is not a function due to pair does not have a common difference

Explanation of Solution

Given:

  $-4,-3,-2,-1,0,1,2,3,4$

Calculation:

  $-4,-3,-2,-1,0,1,2,3,4$

Now, create the relation that is a function

  $0,1,2,3,4$

This relation is a function as this pair has a common difference

Again, create the relation that is not a function

  $-4,0,2,3,4$

This relation is not a function due to pair does not have a common difference

Conclusion:

Therefore, this relation is not a function due to pair does not have a common difference
