Which relation is a function? question 3 options:

{(1, 2); (1, 3); (3, 2); (4, 2)}

{(1, 2); (2, 3); (3, 4); (1, 5)}

{(1, 2); (2, 3); (3, 4); (2, 5)}

{(1, 2); (2, 5); (3, 2); (4, 5)}

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 ^^

For the first one the answer is: 17%

And for the second one the answer is 26%

Step-by-step explanation: I just did the Performance Task and these were correct I know I'm like super duper late but can I get brainliest. 尺蛾翅蛾
