Examples

f = ((1, 0), (0, 5), (0, 2), (8, 9))

$f = ((1, 0), (0, 5), (0, 2), (8, 9))$

Step 1

Since

x = 0

$x = 0$ produces

y = 5

$y = 5$ and

y = 2

$y = 2$ , the relation

(1, 0), (0, 5), (0, 2), (8, 9)

$(1, 0), (0, 5), (0, 2), (8, 9)$ is not a function.

The relation is not a function.

Step 2

The relation

(1, 0), (0, 5), (0, 2), (8, 9)

$(1, 0), (0, 5), (0, 2), (8, 9)$ is not a function, so there is no inverse can be found.

No inverse can be found
