Ryker is given the graph of the function
y= 1/2x^2 - 4 . he wants to find the zeros of the function but is unable to read them exactly from the graph. find the zeros give answer to nearest tenth

x= 2.8   and x= -2.8

Step-by-step explanation:

To find out the zeros, we replace x y with 0 and solve for x

Add 4 on both sides

Multiply by 2 on both sides

8= x^2

Now we take square root on both sides

x= +-

x=2.82843 and x=-2.82843

x= 2.8   and x= -2.8

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
