Which graph represents a function that has the domain (--, -4) U (-4,3) U (3,), has a y-intercept at (0,3), and is increasing on the interval (0,4)?

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

126 maybe. sorry

m∠a is 90°

m∠b is 40°
