Find the solution set X^2+8x=0

x= -8

Step-by-step explanation:

1.Use the quadratic formula

2.simplify

Evaluate the exponent

Multiply by zero

Add the numbers

Evaluate the square root

Multiply the numbers

x=    -8+8

          2

3.seperate the equation

4.solve:

x=0

x=-8

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

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
