Few Questions??
For the function ff given above, determine whether the following conditions are true. Input T if the condition is ture, otherwise input F .
(a) f′(x)<0 if 0<x<2;
(b) f′(x)>0 if x>2;
(c) f′′(x)<0 if 0≤x<1;
(d) f′′(x)>0 if 1<x<4.
(e) f′′(x)<0 if x>4;
(f) Two inflection points of f(x)f(x) are, the smaller one is x=
and the other is x=
I have tried to deal with this but i get some some wrong ans. How should i determine the graph?

1 Answer
a) T
b) F
c) F
d) T
e) T
f)
Explanation:
a) If
b) If
c) If
d) If
e) If
f) An inflection point is the point where the function change of concave to convex or of convex to concave, so if we look we can easy identify the points
