Note: My answer to practice pbl #12 regarding 2f wrongly assumes that f can be any function.
(the problem specifies that f:R→R, while my example is f:Z→ Z). For real-valued functions it is, in fact,
true that f bijective implies 2f bijective. I’ll leave it to you to prove that 2f is surjective.Optional Review/ Q&A Session: Thursday, 2-3:30 in LOW 115.
