I have been trying to solve a question about modified Takagi functions. I couldn't do it so I asked this question here some time ago. First, I included all my work and thoughts but because I didn't get any comments or answers I thought maybe it was too long so then I deleted my work to make the question shorter and therefore easier to read.
But I still didn't get any comments and also not any answers even after offering a bounty.
So, now I am wondering: how can I make a question more appealing? or: why is this question particularly unappealing? And: would it suffice to offer a bigger bounty in the hopes of getting an answer?
