# Section 2.6

## Homework: p. 144; 1-4, 7,9-19 odd, 25,27,35,37,38,39

Note: I am adding numbers 18 and 26 to this assignment.

### In class, homework discussion topics:

• #17: since the limit was of the form $\lim_{x \to \infty}f(x)$, we used $\sqrt{x^2} \Rightarrow x$. If the limit had been to negative infinity, as in $\lim_{x \to -\infty}f(x)$, we would have said $\sqrt{x^2} \Rightarrow -x$.
