Intervals On Which a Function is Increasing and Decreasing

[@h.n.prakul3021]

I was absent for the class on this topic. Then I didn't get how to decide its increasing or decreasing. Before some days, I didn't understand it on youtube. Then I was not able to understand even from one book. Today I got it in one take by your video. Tomorrow is my state board maths preparatory. thank you so much. its really helpfull.

It was of great help

Do we really need to test the f’(x) three times in the sign diagram? Surely two would be plenty

Thank you very much

thnks

[@AmitKumar-up3un]

I understand

[@murillopenna9641]

If I wrote f(x) = (0,infinity) is increasing is right?

[@FartinSpartin]

you lost me at 1 minute... care to explain where the hell you pulled that equation from?

I'm using calculus to find the derivative of the function. This video is about using derivatives to answer this kind of question. If you haven't learned derivatives yet, there are other ways you might answer it, such as using a graph.
