So y must be k higher than this. Here I've drawn the If you have y = 2(x-5)^2 + 2, the 5 is with the x, so if you want to do the same with the ys, you have to subtract 2 on both sides to get y - 2 = 2(x-5)^2, in this case the y would also have to change signs (similar to the point slope form of a linear equation y-y1=m(x-x1). Sure you can add k to both sides to isolate the y variable. y=(x-h)^2+k How do negative values of h represent leftward shifts? Forever.
