Determine which relation is a function.

Step-by-step explanation: The easiest way to tell whether or not this relation is a function is to look at the x-coordinates of the given ordered pairs.

If any of the ordered pairs in this relation have the

same x-coordinate, then the relation is not a function.

In the last relation, all the x-coordinates are different.

So we can say the last relation is a function.

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.
