$(7, 0)$ , $(0, 21)$ , $(9, 0)$ , $(0, 9)$ , $(0, 7)$ , $(21, 0)$

Step 1

Since $x = 0$ produces $y = 9$ and $y = 7$ , the relation $(7, 0), (0, 21), (9, 0), (0, 9), (0, 7), (21, 0)$ is not a function.

The relation is not a function.

Step 2

The relation $(7, 0), (0, 21), (9, 0), (0, 9), (0, 7), (21, 0)$ is not a function, so there is no inverse can be found.

No inverse can be found
