Question 5: Find the limit.
$$ \lim_{x\rightarrow \, -5^+} \frac{-9x}{x+5} $$
Question 6: Find the limit.
$$ \lim_{x\rightarrow \, 2} \frac{-4}{(x-2)^2} $$
Question 7: Find the horizontal and vertical asymptotes of f(x). Then graph f(x).

Question 8: Graph the rational function. Include the graph of the asymptotes.
$$ y=\frac{x^2-25}{x-2} $$
Question 15: Find the horizontal and vertical asymptotes then graph the rational function.
$$ y=\frac{2}{3x+6} $$
