Finite Math Examples

$(0, - 4)$ , $(0, 4)$ , $(0, - 7)$ , $(0, 7)$

Step 1

Since $x = 0$ produces $y = - 7$ and $y = 7$ , the relation $(0, - 4), (0, 4), (0, - 7), (0, 7)$ is not a function.

The relation is not a function.

Step 2

The relation $(0, - 4), (0, 4), (0, - 7), (0, 7)$ is not a function, so there is no inverse can be found.

No inverse can be found
