Re-write the quadratic function below in Standard Form
y= 4(x + 8)(x - 2)

4x^2+24x-64

Step-by-step explanation:

First you multiply (x+8) by (x-2). You can use this using the FOIL method which stands for first, outer, inner, last. Through this method you would multiply x by x first and get x^2, then x by -2 and get -2x, then 8 by x and get 8x, and finally 8 by -2 and get -16. You then add this all together and get x^2-2x+8x-16 or x^2+6x-16.

Now all you have to do is multiply each term by 4 and get 4x^2+24x-64 using the distributive property.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

probably .5

i can on others if necessary.
