I don't know how to solve and I have to show my work on the questions please help

Solution:

√y - ⁴√y - 6 = 0

(⁴√y)² - ⁴√y - 6 = 0

u² - u - 6 = 0

u = 3 and u = -2

⁴√y = 3

y = 81

⁴√y = -2

y ∈ R

y = 81

Best of Luck!

The value of y is 81.

Step-by-step explanation:

See the steps below :

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
