Perform the operation and state the domain. let f(x)= 3x - 7 and g(x)= x - 5
13) f(x)+g(x). 14) f(x) * g(x)
15) f(x)/g(x). 16) g(f(x))

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

i think the answer is b
