Can someone double-check my work for this problem??

Which equation shows a vertical stretch of 2, a reflection over the x-axis, then a shift left 3 units and down 4 units?

y= (-2/x+4)-3
y= (-2/x+3)-4
y= -[(2/x+4)-3]
y= -[(2/x+3)-4]

I know the general form is y=(a/x-h)+k, I think the answer is D.

So i got D, but why is there a negative outside parenthesis. I mean isn't vertical stretch |a|>1, horizontal by h, and vertical by k??

Yes D is correct.  The negative only controls the direction the graph opens.  So it has nothing to do with the stretch or the horizontal or vertical stretch.

Oh, got it thanks!
