Which relation is a function?
I will give brainliest to right answer

2nd graph is a function

Step-by-step explanation:

To find graph is a function or not, draw a vertical line. if that line cuts your graph more than once, then it's not a function.

If you draw a vertical line through circled graph, it will cut your graph at two points. so it's not a function

If you draw a vertical line through 2 nd graph it will cut your graph at only one point. therefore it's a function.
