From the graphs in Fig. 10-8, indicate which graphs are (1) increasing for all x, (2) decreasing for all x, (3) convex for all x, (4) concave for all x, (5) which have relative maxima or minima, and (6)

which have inflection points.

(1)

c, f; increasing for all x.

b, d; decreasing for all x.
(3)

a, d; convex for all x.
(4)

c, e; concave for all x.
(5)

a, e; exhibit a relative maximum or minimum.
(6)

b, f; have an inflection point.
