For a relation to be a function it must be [tex]<b>one-to-one or many-to-one.</b>[/tex]

[tex]<b>One-to-many</b>[/tex] relation is not a function.

In the above options, C is [tex]<b>One-to-many</b>[/tex] relation therefore cannot be a function.

The reason is that 3 alone maps onto -2 and 5, in the ordered pairs (3,-2) and (3,5). This disqualifies it from being a function.

Hence the graph of this relation will not pass the vertical line test

[tex]<b>The correct answer is C</b>[/tex]
