BRAINLIEST. No spam -_-

Step-by-step explanation:

we are given

To find x-intercept means we have to find zeros

and for finding zeros , we will use quadratic formula

and we have it has two x-intercepts  

so, it's discriminant must be greater than 0  

so, we will find discriminant

now, we can compare with

and then we can find a , b and c

a = 3, b = 7, c = m

now, we can find D

It has two x-intercepts

so,

now, we can solve for m

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
