The circle below is centered at the point (2, -1) and has a radius of length 3. What's its equation? A. (x-1)²+(y+2)²=9
B. (x-2)²+(y+1)²=3²
C. (x+1)²+(y-2)²=9
D. (x+2)²+(y-1)²=3²

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
