Relations mapping domain values to range values can be described as one-to-one or not one-to-one. If one x-value maps to many y-values (one-to-many), does the relation represent a function? If the x- and y-values are reversed, does the relation represent a function? Explain.

If the relation is not one-to-one, does the relation represent a function? If the x- and y-values are reversed, does the relation represent a function? Explain.
