# Thread: Limits in the epsilon delta proof

1. ## Limits in the epsilon delta proof

how do i find the delta neighborhood with the digits 1, 9, 3, and 7 assuming these make some sort of function. be creative.

Please do not offended. But that makes no real sense.

$\displaystyle (0.999,1.001)$ is a delta neighborhood of $\displaystyle 1$ where $\displaystyle \delta=0.001$.

So what is the real question?

i'm not exactly sure myself. I am playing a riddle game online, and i think the answer involves finding something to do with delta neighborhoods and either creating a function or finding a limit. the only numbers i was given were 1, 9, 3, and 7. there was no direction on what to do with them. i was thinking possibly the function being 19x+b = 37 or something. I apologize if this seems vague, but I was not given much to work with.
