1. Given:
7- 4r
r(r +8)(r – 2)
8(7x – 4)
(r + 2)4
f(x) =
(x+ 2)2
with f'(r) =
and f"(r) =
(r +2)3
a. Find the domain of f and the intercepts of the graph of f.
b. Using limits, show that r= -2 and y = r- 8 are asymptotes of the graph of f.
c. Identify the critical mumbers of f and the possible points of inflection of the graph of f.
d. Construct a table of signs for f' and f". From here, specify the following:
i. the intervals on which the graph of f is increasing, decreasing, concave up, and concave
down, and
ii. the values ofr at which f has relative extrema, inflection points, and vertical asymp-
totes (if any).
e. Sketch the graph of f with emphasis on concavity. Label all the intercept points, relative
extremum points, and inflection points with their coordinates. Show the asymptotes of
the graph of f and label them with their respective equations.
