Which statement describes the mapping?
x, negative 1, 0, 2, 3, y, 1, 4, 7
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.
