take two one sided limits approaching 1. On the left side, x < 1, so use that part of the function. $\lim_{x \rightarrow 1^{-}}f(x)=\lim_{x \rightarrow 1^{-}}3x-1$

3. anonymous

these are my choices: 2 1 0 does not exits

4. anonymous

ok. can you do the limit above?

5. anonymous

don't know how

6. anonymous

You're taking a limit as x approaches 1, so plug in 1 for x

7. anonymous

so its 2?

8. anonymous

yes

9. anonymous

oh thank you!
