Which statement describes the mapping?

• The mapping represents y as a function of x, because each y-value corresponds to exactly one x-value

• The mapping does not represent y as a function of x, because two of the x-values correspond to the same y-value

• The mapping represents y as a function of x, because each x-value corresponds to exactly one y value.

• The mapping does not represent y as a function of x, because there are more x-values than different corresponding y values.
