Find approximations for the input where the functions share a solution.

x ≈ 0, x ≈ 2.5

Step-by-step explanation:

The left point of intersection is very near the y-axis, where x=0.

The right point of intersection is somewhat below the midpoint between x=2 and x=4. It seems to be just about at the midpoint between that midpoint (x=3) and the line at x=2. We estimate the value at about x=2.5.

If we knew the actual function definitions, we could solve for the points of intersection.

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
