They asked for a surjective function that isn’t injective. Are you sure I am correct?Do you have a reason to think it might either be injective, or not be surjective?
It looks good to me.
I think I just have a loss of confidence that’s why I askedThey asked for a surjective function that isn’t injective. Are you sure I am correct?
Here is an interesting function: ϕ(n)=⌊2n+1⌋ [That is the floor function].Please help would appreciate it !!
What does injective mean? Does your function satisfy the definition. Why?I think I just have a loss of confidence that’s why I asked![]()
