Answer:
x^2y^2 +9xy^2-xy-27y-6
Step-by-step explanation:
(xy+9y+2) (xy-3)
Each term of second bracket will be multiplied with the terms of first bracket
= xy(xy+9y+2) -3(xy+9y+2)
= x^2y^2+9xy^2+2xy-3xy-27y-6
=x^2y^2+9xy^2-xy-27y-6
That is called the dependent variable. It depends upon the value of the independent variable.
f(x)=y
So we can see by inspection that the dependent variable y value depends upon the input value of the independent variable x
