Question

What does it mean when doing a first derivative interval chart when there are two positives in between the local extrema? So if XE(-infinity,3) is positive and (3,infinity) is positive too, it doesn't mean there is a local max or even a min. How is that and what does it mean when there are two positives or even negatives?
