Yes

Step-by-step explanation:

To determine whether a relation is a function or not, we can do a vertical line test. First, get something like a ruler, put it vertical, then scan it on the relation. If the ruler hits one point of the line, then it is a function. If the ruler hits two points at once, then it is not a function. This passes the vertical line test, because when the ruler hits the relation it only hits one point at a time, making it a function. I hope this helps, I hope it's not wrong but I don't think it is.

i hope this is what you were looking for.
