Homework Statement:
Show that if f: A -> B and E, F are subsets of A, then f(E U F)=f(E) U f(E).
Relevant Equations:
Basic proof stuff.
Here is my solution. I used mathjax to type it up in Overleaf. I feel like it makes sense, but I also have a feeling I might have "jumped the gun" with my logic. If it is correct, I would appreciate feedback on how to improve it. Thanks!
