CHAPTER ONE
Exercises
1. Since t represents the number of years since 2010, we see that ƒ (5) represents the
population of the city in 2015. In 2015, the city’s population was 7 million.
2. Since T = ƒ (P ), we see that ƒ (200) is the value of T when P = 200; that is, the thickness
of pelican eggs when the concentration of PCBs is 200 ppm.
3. If there are no workers, there is no productivity, so the graph goes through the origin. At
first, as the number of workers increases, productivity also increases. As a result, the curve goes
up initially. At a certain point the curve reaches its highest level, after which it goes downward;
in other words, as the number of workers increases beyond that point, productivity decreases.
This might, for example, be due either to the inefficiency inherent in large organizations or
simply to workers getting in each other’s way as too many are crammed on the same line. Many
other reasons are possible.
4. The slope is (1 − 0)∕(1 − 0) = 1. So the equation of the line is y = x.
5. The slope is (3 − 2)∕(2 − 0) = 1∕2. So the equation of the line is y = (1∕2)x + 2.

12. (a) is (V), because slope is positive, vertical intercept is negative
(b) is (IV), because slope is negative, vertical intercept is positive
(c) is (I), because slope is 0, vertical intercept is positive
(d) is (VI), because slope and vertical intercept are both negative
(e) is (II), because slope and vertical intercept are both positive
(f) is (III), because slope is positive, vertical intercept is 0
