Find any region that is mapped bijectively to $\{w\colon \Re w\ge |\Im w |, \ 0< |w|\le 2\}$ by the map $w=e^z$. Draw both of them.

You can modify your post and remove unwanted attachments. What are domains (you draw several), which one is correct? You need to state it explicitly rather than leaving to guesses.
