Which is not a function

A function is of the form

Assume a function is:

In simple terms:

For an ordered pair to be regarded as a function, no x value must be repeated

Analyzing the options:

1.

This is a function because none of the x values (-3, 8, 0 and -9) appeared more than once

2.

This is a function because none of the x values (5, -3, 0 and -9) appeared more than once

3.

This is a function because none of the x values (9, -5, 5 and 6) appeared more than once

4.

This is not a function because one of the x values (2) appeared more than once.

i.e.

  and  

first one is a: renaming a fraction. second one is c: de-c
