Media Image

What is the sequence of transformations for the image given?

Reflect over the x-axis, translate (x+8,y)

Reflect over the x-axis then translate (x+6, y)

Reflect over the y-axis then (x+1, y+1)

Translate down 4 (y-4) and to the right 5 (x+5)

Answer explanation

Media Image

The orientation of the labels indicate that the figure was reflected, not rotated, as they are mirrored from the original preimage.


Then, a translation would result in the figure being positioned where it is shown.
