What I did is: $|x-3| \lt 1 \Rightarrow 2 \lt x \lt 4 \Rightarrow 2 + 3 \lt x + 3 \lt 4 + 3 \Rightarrow 5 \lt x + 3 \lt 7$.. I don't know if that even makes sense. Do you mind showing some algebraic steps? Jan 24 comment How do I find the delta analytically for $f(x)$ with a degree other than $1$ Wow I must be really dumb as I still can't wrap my head around this.. so basically what you're saying is that $|x-3| \lt 1 \Rightarrow |x+3| \lt 4$? Jan 24 comment How do I find the delta analytically for $f(x)$ with a degree other than $1$ I'm trying to solve a similar problem but can't seem to figure out why $|x+3| \le 4$ if I choose $\delta \le 1$? Nov 7 awarded Nice Question Nov 1 comment How to Improve Mathematical Thinking and General Problem Solving Skills? Hmm not exactly sure how to answer this. Just questions in general on any topic say textbook practice problems or questions in: projecteuler.net/problems although these are more math puzzle types.
