Would someone mind checking my proof? Intro Real Analysis

In summary, asking someone to check your proof in Real Analysis can help identify errors and improve your understanding of the subject. When presenting your proof for review, clearly state your assumptions, definitions, and theorems used in a logical and organized manner. If someone finds an error, use their feedback to correct and strengthen your understanding. It is acceptable to ask multiple people for feedback, as it can provide different perspectives. To improve proof-writing skills, practice regularly, seek feedback, and analyze well-written proofs in textbooks or academic papers.

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!
