Hi how do I go about beginning this question? I'm not entirely sure how the hint helps. If you wouldn't mind just walking me through maybe (b) for the y-axis and one of the circle equations, that would be great!

3.13. Let f (z) = 22%. Draw two graphs, one showing the following six sets in the z-plane and the other showing their images in the w-plane. Label the sets. (You should only need to calculate the images of 0, :|:2, co and 1 i; remember that Mobius transformations preserve angles.) (a) the x-axis plus 00 (b) the yaxis plus 00 (c) the line at = y plus 00 (d) the circle with radius 2 centered at 0 (e) the circle with radius 1 centered at 1 (f) the circle with radius 1 centered at 1
