If f
(
x
)
=
2
(
−
x
+
1
)
3
, what is the value of
f
(
−
1
)
?

hmm

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

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
