To determine whether the function has an inverse, we need to check if the function is one-to-one (injective). A function is one-to-one if no two different ordered pairs have the same second element.
We can list the pairs from the function:
1. (6, 2)
2. (3, 1)
3. (1, 6)
4. (4, 2)
Next, we look at the second elements of each ordered pair:
- The second elements are: 2 (from (6,2)), 1 (from (3,1)), 6 (from (1,6)), and 2 (from (4,2)).
We can see that the second element "2" is repeated in the pairs (6, 2) and (4, 2). This means that the function is not one-to-one.
Since the function is not one-to-one, it does not have an inverse.
So the correct choice is:
**B. The function does not have an inverse.**
