What set of transformations could be applied to rectangle abcd to create a'b'c'd'? reflected over the x-axis and reflected over the y-axis reflected over the y-axis and rotated 180° reflected over the x-axis and rotated 90° counterclockwise reflected over the y-axis and rotated 90° counterclockwise

Answer
Reflected over the x-axis and reflected over the y-axis.

Explanation.
When the rectangle ABCD is reflected along the x-axis, the images of ABCD will be A''(-4,-2), B''(-4,-1), C''(-1,-1) and D''(-1,-2). 
When the rectangle A'', B'', C'' and D'' is reflected on the y-axis, it will exactly map on to A'B'C'D'. 

So, the correct answer from the choices is "Reflected over the x-axis and reflected over the y-axis".
