Check that for each value of y , there is only one value of x . Check that for each output, there is only one input. Check that for each output, there is only one input. Check that for each input, there is only one output. Check that for each input, there is only one output. Check that a diagonal line could move across the y-axis and only intersect the graph of the relation in one spot at a time.

The option that best describes how to determine if a relation is a function is: Check that for each input, there is only one output.
This is because, in a function, every input (or x-value) must map to exactly one output (or y-value). The other options either misinterpret the concept or apply to other principles.
