## Need help proving continuity for $\frac{2x}{3x-1}$ at $x=1$ using Epsilon-Delta

The function is given as: $\frac{2x}{3x-1}$ I must prove continuity at $x=1$. I understand the definitions using the Epsilon Delta proof but my issue comes when I arrive at $|f(x)-f(1)|=|\frac{1-x}{3x-1}|=\frac{|x-1|}{|3x-1|}$< $\epsilon$. I know I must relate that result with $|x-1| < \delta$ but I am stumped on how to bound the denominator of […]
