\Graph the function
:

Observe the graph.
\In the intervals
and
, the function
is positive then the antiderivative
is increases.
In the intervals
and
the function
is negative then the antiderivative
is decreases.
The function
changes its sign from positive to negative at
, then the antiderivative
has a local maximum.
The function
changes its sign from negative to positive at
, then the antiderivative
has a local minimum.
The function
changes its sign from positive to negative at
, then the antiderivative
has a local maximum.
The antiderivative
has a inflection point, where the function
has either local maximum or local minimum values.
Therefore the antiderivative
has a inflection points at
and
.
