Answer: The second image
Step-by-step explanation: Using the vertical line test, you can check if a relation is a function. If you draw a vertical line and it passes through 2 points, then the relation is not a function. For the first image, you can see that when you draw a vertical line through (-1,-1), it will also pass through (-1,3), so it is not a function. For the third image, you can see that when you draw a vertical line through (-2,-2), it will also pass through (-2,1). For the fourth image, you can see that when you draw a vertical line through (-1,0), it will also pass through (2,0). For the second image, if you were to draw a vertical line through each point, that point would be the only point that it passes through. Therefore, the second image is the only image where the relation is a function.
