Answer: First option, the graph of the relation passes the vertical line test.
Step-by-step explanation:
A function is a relation that maps elements from a set (the domain, the x-values) into elements from another set (the range, the y-values)
Where the only condition we have is that each element from the domain can be mapped into only one element from the range.
So if we draw a vertical line at any point of the graph, it can intersect the graph of the function a maximum of one time. (this is known as the vertical line test)
Then the correct option is that the graph of the relation passes the vertical line test.
