Grace and lily have a diferent point of view about the transformation on cube that is shown above.
grace states that it is a reflection about the imaginary axis and a dilation of factor of 2. however, lily argues it
should be a 90° counterclockwise rotation about the origin with a dilation of a factor of 2.
a. who is corect? justify your answer.
b. represent the above transformation in the form l(x, y) = (aa− b, b+ aa).
