    None of these is correct. I think you probably meant to type: A. Y = -sqrt(x+4) +3 B. Y = -sqrt(x-3) + 4 etc.

    To shift a curve 3 units to the right, you replace *every* x in the equation by x-3 (NOT x + 3)! When you work with transformations involving x, it goes against your intuition! Shifting a curve up/down is much more intuitive: For example, if you want to shift " y = stuff" up 4, you'd get the new equation "y = stuff + 4". Now you try it...
