What is the constant of variation for the quadratic variation: 0.1y = 3x to the 2 power? i need !

0.1y = 3x^2

divide each side by 0.1

y = 3x^2/0.1

factor the right side to get y = 30x^2

this can't be written in the form y = kx so y does not vary directly with x

 so there is no constant of variation.

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
