Observe the graph $\"\"$ .

In the interval $\"\"$ , the function $\"\"$ is negative then the antiderivative $\"\"$ is decreases.

In the interval $\"\"$ , the function $\"\"$ is positive then the antiderivative $\"\"$ is increases.

In the interval $\"\"$ , the function $\"\"$ is negative then the antiderivative $\"\"$ is decreases.

$\"\"$ .

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 $\"\"$ .
