The graph of f(x), shown below in pink, has the same shape as the graph of g(x) = x2, but it is stretched vertically. what is its equation?

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.

hope this < 3
