Note: Problems 16.7–16.8 refer to the function .
16.8 Graph g(x) using the table of values completed in Problem 16.7.
According to the table of values in Problem 16.7, the graph of g(x) passes
through the following points: , (–2,–1), (–1,–2), (1,2), (2,1), and .
Additional points may be used to determine the shape of the graph, illustrated
in Figure 16-4, if necessary.

Theres
a better way to
graph functions with
x in the denominator.
Check out Problems
16.30, 16.33, and
16.34.
Unless
knew that functions
with a denominator
of x looked like Figure
16-4, the six points you
got from the table
of values probably
arent enough to draw
the graph. When that
happens, pick more
values of x (like –4, –5,
6, 4, 5, and 6) and plot
more points.
