Derive the first and second derivatives to find the specific points, then look at the signs of each.

#### Explanation:

With a cubic equation you will have more than one. From calculus you can derive the first and second derivatives to find the specific point.

Then apply the inflection point rules – the graphs show why the values are what they are.
