${(1, 5), (2, 6), (1, 7), (4, 8)}$

Step 1

Since $x = 1$ produces $y = 5$ and $y = 7$ , the relation $(1, 5), (2, 6), (1, 7), (4, 8)$ is not a function.

The relation is not a function.

Step 2

The relation $(1, 5), (2, 6), (1, 7), (4, 8)$ is not a function, so there is no inverse can be found.

No inverse can be found
