For the function f(x) = -2(x + 3)2 -1, identify the vertex, domain, and range. (2 poin

See below in bold.

Step-by-step explanation:

f(x) = -2(x + 3)^2 - 1

Comparing this  to the standard  f(x) = a(x - b)^2 + c where (b, c) is the vertex.

The vertex  is (-3, -1).

The domain is All real x.

The range is f(x) ≤ -1.

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
