I'm doing a review in calc I to prepare for calc II. I'm now applications of derivatives (optimization). Okay so when I have the function I need to optimize, I need to take the derivative and find the critical point of the first derivative. But sometimes theres more than one critical point. Is there any sort of test that I can do to find which critical point I should use.(adsbygoogle = window.adsbygoogle || []).push({});

--thank you.
