With hints and comments:

PC2 Quiz 10 – Half life and compound interest. First read p181. Then, if you still are shaky, review p182 ex3 and the table on p188

PC2 Quiz 11 – Assorted log laws. Only the first 3 questions were mandatory. Review 5-5 and 5-6, esp. the table on 197 and the examples on 198 – 199.

PC2 Quiz 12 – Adding and subtracting rational expressions. Few issues here. For those of you who canceled from a sum, please don’t.

PC2 Quiz 13 – Partial fraction decomposition. Rewrite the rational expression as the sum of several rational expressions. Find the denominators by factoring. Express the numerators as A or Bx + C or , making sure that the degree of the numerator is one less than the degree of the denominator. The first bonus question involves three denominators. The second bonus question involves combining the original denominator the same expression, not squared. The result will yield numerators without x’s

PC2 Quiz 14 -

• Question 1. Look at the graph, and talk about what the function might be. You should recognize the shape as or some variant thereof. Discuss the asymptotes.
• Question 2. You have the equation and the graphs. point to the different part of the graphs, and associate them with the equation. What would this look like if the absolute value were not there? What would this look like if the fraction were not there? (very much like one of the graphs, not at all like the other). Why do some of the elements become more visible in one graph than in the other? Are there asymptotes?  (you may use diagrams or other graphs in your explanation)
