The equations y=√x and y=x^2-1. the system of equations is equal at a) (1.5, 1.2) b) (-1.5, -1.2) c) (1.5, -1.2) d) (-1.5, 1.2)

f

step-by-step explanation:

f

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
