Which statement about this mapping is true? The mapping does not represent y as a function of x, because 4 y-values are related to 1 x-value.

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

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

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

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

Step-by-step explanation:

Becuase y represents the function of x

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
