Answer:

The last one

Step-by-step explanation:

For something to be a function, the x-value is suppose to have only one y-value. All of them except for the last one has a x-value that has 2 y-values

The first 3 options are incorrect because they all have multiple x values that are the same for example like (1,7) to (1,8) so having something like this occur means the function ins't a function so the only one that doesn't repeat any of it's x values is the 4th option. Hope this helps out ^^
