Question about transform function Geometry App

Symbolic:

GA, plot function (x^2)

GB, translation (2,GA)

Plot okay, GB plotted 2 units horizontal to the right

Numeric:

Equitation (GA) (y -x^2) = 0

Equitation (GB) (x^2-4.*x-y+4.) = 0 -> Okay!

Symbolic:

GA, plot function (x^2)

GB, translation (0-2i,GA)

Plot okay, GB plotted 2 units vertical down

Numeric:

Equitation (GA) (y -x^2) = 0

Equitation (GB) 1 = 0 -> WHY?

What must I do (or change some settings?) to get the right answer?

When I use I line in stead of a plot function I get the right answer!! (Not the 1 = 0)

Sorry, but my "think window" is very small!
