Chapter 2.2, Problem 90PE
Data from a 20-yr study show the number of new AIDS cases diagnosed among 20- to 24-yr-olds in the United States x years after the study began.
a. Approximate the interval(s) over which the number of new AIDS cases among 20- to 24-yr-olds increased.
b. Approximate the interval(s) over which the number of new AIDS cases among 20- to 24-yr-olds decreased.
c. How many turning points does the graph show?
d. Based on the number of turning points, what is the minimum degree of a polynomial function that could be used to model the data? Would the leading coefficient be positive or negative?
e. How many years after the study began was the number of new AIDS cases among 20- to 24-yr-olds the greatest?
f. What was the maximum number of new cases diagnosed in a single year?

17. Suppose we know that the graph below is the graph of a solution to dy/dt = f(t).
(a) How much of the slope field can
you sketch from this information?
[Hint: Note that the differential
equation depends only on t.]
(b) What can you say about the solu-

(b) Find the (instantaneous) rate of change of y at x = 5.
In the previous part, we found the average rate of change for several intervals of decreasing size starting at x = 5. The instantaneous rate of
change of fat x = 5 is the limit of the average rate of change over the interval [x, x + h] as h approaches 0. This is given by the derivative in the
following limit.

-
f(x + h) − f(x)
h
The first step to find this limit is to compute f(x + h). Recall that this means replacing the input variable x with the expression x + h in the rule
defining f.
f(x + h) = (x + h)² - 5(x+ h)
