what does double reflection mean on a quadrant chart

Question

If the following double reflection was performed. Rx=1 o Rx=-4 the resulting image would end up at ?

Answer 1

It depends on the where the image originated

If it was in the first quadrant (top right)

and it was a triangle with the coordinates (3,1) (5,1) (4,2)

the first reflection over X=1 would result in these coordinates (-1,1) (-3,1) (-2,2)

in the 2nd quadrant, moving to the right

the second reflection over X=-4 would move it further to the right, (-7,1) (-5,1) (-6,2)

remaining in the 2nd quadrant
