Chapter 1: Q1. (page 45)

Determine whether each relation is a function. Explain.
${(2, 1), (3, - 2), (3, 1), (2, - 2)}$

Short Answer

Expert verified

This relation is not a function.

Step by step solution

Step 1. Given.

The given relation is: ${(2, 1), (3, - 2), (3, 1), (2, - 2)}$

Step 2. To determine.

We have to find if the given relation is a function.

Step 3. Calculation.

For a relation to be a function, we must have only one y value for each x value.

For this relation:

For x = 2, we have y = 1 and y = –2.

For x = 3, we have y = 1 and y = –2.

So, for each x value, there are two y values. This implies that this relation is not a function.
