Solve for the function below.
f (x)=3x – 6
where x = 5
O -4
O 21
O 2
O 9

its the fourth option

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

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
