Examples

(1, 1)

$(1, 1)$ ,

(2, 2)

$(2, 2)$ ,

(3, 3)

$(3, 3)$ ,

(4, 3)

$(4, 3)$ ,

(1, 2)

$(1, 2)$

Step 1

Since

x = 1

$x = 1$ produces

y = 1

$y = 1$ and

y = 2

$y = 2$ , the relation

(1, 1), (2, 2), (3, 3), (4, 3), (1, 2)

$(1, 1), (2, 2), (3, 3), (4, 3), (1, 2)$ is not a function.

The relation is not a function.
