If this is how the function looks like $$y=\sqrt{4x-4}$$ then 4x-4 must be grater or equal 0.
Solve it.

@YOLO_KING can you help me out? :)

anonymous · Answer

The answer is b because you are putting the grater than or equal to zero before the 2x-2 then you add 2 to 0 which gets you positive two. now you divide 2x with two; and you get the answer b. make sence
