The binomial expansion of (x-2y)^3 is__ PLEASE HELP

A) x^3+3x^2y+3xy^2+y^3

B) x^3-3x^2y+3xy^2-y^3

C) 2^2(x^3-3x^2y+3xy^2-y^3)

D) x^3-6x^2y+12xy^2-8y^2

The answer is D) x^3-6x^2y+12xy^2-8y^2

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

the answer is (-4,-4)

hope this ! : d
