i have a question....say u have a point (15,-1) and you get it from doing a verticle compression by 1/2 and a verticle reflection...wat would the original point be? to find it you would have to undo the verticle compression and reflection from

(15,-1)...how would u do that?

(15,-1) is the result of a vertical reflection, so before that it was (15,1)

(15,1) is the result of a compression by 1/2 so before that it was (30,1)
