[will mark as brainliest if correct] for which function is f(x) equal to f^-1(x)? a. f(x)=x+6/x-6 b. f(x)= x+2/x-2 c. f(x) x+1/x-1 d. f(x) x+5/x-5

the 3rd one is the correct answer

Step-by-step explanation:

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
