# Math Help - Limits

1. ## Limits

This is probably pretty easy and I'm just over-thinking it, but I have no clue what to do for this problem.

If $\lim_{x \to3} (3x-2)=7$, find $S$ such that $|(3x-2)-7|<0.003$ whenever $0<|x-3|

Note that $\left|(3x-2)-7\right|=\left|3x-9\right|=3{\color{red}\left|x-3\right|}<0.003$ whenever $0<{\color{red}\left|x-3\right|}

With this, what is S?

3. I think S is just a symbol for whatever that number is that is supposed to fit in the last equation.

But so therefore, S = 0.001?
