Choose the expression that represents a quadratic expression. 6x^4 − 5x^3 + 3x^2 −7x − 8
5x^3 + 3x^2 −7x − 8
2x^2 + 3x − 1
3x − 1

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
